By the way, like what was indicated by the above-mentioned patent documents 2, based on a demand from a user, etc.,
Each manufacturer or the like appropriately adjusts the viewing angle of the first video and the second video. However, the viewing angle varies depending on the manufacturer and product, and it is impossible to specify the viewing angle on the conventional two-screen display panel.
It is not known how the viewing angle is adjusted in the panel manufacturing process. Therefore, the panel manufacturer does not know which product has set the viewing angle, and the only way to confirm that it is a proper product is to actually check the display panel by operating it. .

The present invention has been made in view of the above problems, and an object of the present invention is to look at the viewing angle of the two-screen display panel that is adjusted by a slight difference in the restriction position of the light shielding barrier of the light shielding barrier substrate. It is to provide a two-screen display panel that can be confirmed.

Sometimes loss of driver and FPC occurred. However, if the present invention is applied, since the two-screen display panel can be inspected alone, the loss of the driver and the FPC does not occur. Further, in this two-screen display panel, the difference between a plurality of forms is only the configuration of the light-shielding barrier of the light-shielding barrier substrate, so that a common display substrate can be used. Further, since the opening can be easily formed by removing the light blocking barrier, the number of manufacturing steps does not increase.

In the above invention, it is preferable that the openings formed in each of the plurality of determination regions have different shapes.

As shown in FIGS. 1 and 2, the two-screen liquid crystal display panel 1 according to the first embodiment is formed by laminating a liquid crystal display substrate 10 and a light shielding barrier substrate 20 and bonding them using an adhesive 41 made of a transparent material. Is. Further, polarizing plates 42 and 43 are attached to the front and back surfaces of the laminate of the liquid crystal display substrate 10 and the light-shielding barrier substrate 20, respectively, and a backlight BL is attached to the back surface of the polarizing plate 43 attached to the back surface. It is arranged.

As the liquid crystal display substrate 10, a substrate having the same structure as that used in a known liquid crystal display device can be used. Briefly describing the configuration, an array substrate on which various wirings are formed on the surface, and a light shielding layer BM and a plurality of colors such as R (red), G (green), and B (blue) color filter layers are provided on the surface. The color filter substrate is provided, these substrates are opposed to each other and bonded together with a sealing material, and liquid crystal is sealed inside.

And the area | region where the liquid crystal of this liquid crystal display substrate 10 was enclosed is display area DA which displays an image
And the display frame F as an area where wiring is routed around the outer periphery of the display area DA
A. The liquid crystal display substrate 10 is larger than the light shielding barrier substrate 20, and includes a projecting portion 10a that is exposed to the outside in a state where the light shielding barrier substrate 20 is laminated on the liquid crystal display substrate 10, and this projecting portion 10a. LCD driver and FPC (
This is the area where flexible printed circuits are attached.

Each subpixel of the liquid crystal display substrate 10 is divided into a first image and a second image, for example, a navigation image and a video reproduction image. Specifically, for example, sub-pixels that display the first image and sub-pixels that display the second image are arranged alternately along the horizontal direction. A color filter layer is provided for each of these sub-pixels. In FIG. 2, the color filter layer of the sub-pixel that displays the first image is provided with the codes RL, GL, and BL for each color, and the color filter layer of the sub-pixel that displays the second image. Is shown with a symbol RR, GR, BR for each color.

The light shielding barrier substrate 20 includes a light shielding barrier 21 formed of a black matrix or the like. The light shielding barrier 21 is applied to the entire surface of the light shielding barrier substrate 20, and the first
For example, the light transmitted through the sub-pixel for displaying the second image is transmitted only to the seat on the left side of the two-screen liquid crystal display panel, for example, and the light transmitted through the sub-pixel for displaying the second image is transmitted to the other, for example, 2
The viewing direction is regulated so as to transmit only to the seat side located on the right side of the screen liquid crystal display panel 1. More specifically, for example, a plurality of slits 22 are formed at predetermined intervals along the vertical direction in the light shielding barrier 21 so that light passing through the slits 22 can be viewed only from a specific viewing area. It is what.

According to the two-screen liquid crystal display panel including the liquid crystal display substrate 10 and the light shielding barrier substrate 20 configured as described above, as shown in FIG.
And the viewing direction of the second image is restricted, and different images can be displayed on the left and right.
Note that most conventional two-screen display panels have their viewing directions regulated at equal angles from the center line CL as shown in FIG. 2 will be described below as a first mode.

The two-screen liquid crystal display panel 1 according to the present embodiment includes a first and a second in a part of the display frame FA, more specifically, at a substantially central portion of a pair of short sides forming the left and right side surfaces in the frame-shaped display frame FA. Discriminating areas 30L and 30R are provided. The first and second discriminating areas 30L and 30R are areas for confirming the relative positions of the liquid crystal display substrate 10 and the light shielding barrier substrate 20, and when actually mounted on an in-vehicle navigation device or the like, Provided in the part covered by the housing. Note that the positions of the first and second determination areas 30L and 30R may be any location within the display frame FA, and the number is not limited to two and may be three or more. good.

Since the display frame FA portion of the liquid crystal display substrate 10 is usually a portion that does not contribute to display, the entire surface is covered with a light shielding layer BM provided on the color filter substrate. However, some of the positions corresponding to the first and second discrimination regions 30L and 30R are not provided with the light shielding layer BM, and instead, the discrimination means, specifically, the color of any one of R, G and B colors. A filter layer 12 is provided. The color filter layer 12 has different colors depending on whether the color filter layer 12 is provided in a part of the position corresponding to the first determination area 30L and the color filter layer 12 provided in a part of the position corresponding to the second determination area 30R. It is preferable to use one. By the way, in the present embodiment, the R (red) color filter layer 12 is used for the former, and the G (green) color filter layer 12 is used for the latter.

Preferably, a reflector 11 made of aluminum or the like is disposed on the back side of the color filter layer 12. The color filter layer 12 formed in a part of the first and second discrimination regions 30L and 30R is formed with the same material and the same process as the color filter layer generally used in the display region DA. Therefore, the manufacturing man-hours will not increase.

Further, the display frame FA of the light shielding filter substrate 20 is usually shielded from light like the liquid crystal display substrate 10 by extending the light shielding filter 21 made of a black matrix in a solid shape. However, also in this light shielding filter substrate 20, the first and second discrimination regions 30L, 30R
The light shielding filter 21 is not provided in a part of the position corresponding to the positions 23L and 23R.
(See FIGS. 3 and 4). The openings 23L and 23R are formed by the light shielding filter 21.
Since the slits 22 may be formed at the same time, the manufacturing man-hour is not increased. Further, the shapes of the openings 23L and 23R may be a simple rectangular shape. However, in order to make the relative positional relationship between the liquid crystal display substrate 10 and the light shielding filter substrate 20 easier to understand, an arrow ( It is preferable to form in the shape of FIG. Of course, in the case of such an arrow shape, the shapes of the two openings 23L and 23R are different from each other.

In the two-screen liquid crystal display panel 1 having the above configuration, the configuration when the viewing directions of the first and second images are changed will be described in detail below.

First, the two-screen liquid crystal display panel 1 as the first mode shown in FIG.
Is set at an equal angle. In this case, when the first and second discriminating regions 30L and 30R are viewed from the surface of the two-screen liquid crystal display panel 1, the two openings 23L and 23R are simply shielded by the light shielding layer BM of the liquid crystal display substrate 10. Black display.

Next, as a second mode in which the viewing direction is changed, a case where the viewing direction of two images is shifted to the left will be described with reference to FIG.
In the two-screen liquid crystal display panel 1 of the second embodiment, the light shielding filter substrate 20A is different from the light shielding filter substrate 20 shown in the first embodiment. That is, as shown in FIG. 3, the light shielding filter substrate 20A is located at a position slightly shifted to the left with respect to the liquid crystal display substrate 10.
Is provided. In this case, as apparent from the comparison between FIG. 3 and FIG. 2, the viewing directions of the first and second images are both shifted to the left. In this case, both the first image and the second image can be easily seen from the user sitting on the left seat, and the second image displayed on the right side can be visually recognized from the user sitting on the right seat. The first image displayed on the left side is not easily visible.

When the viewing direction of the two images is shifted to the left as described above, when the two-screen liquid crystal display panel 1 is viewed from the front surface, the second discrimination region 30R out of the first and second discrimination regions 30L and 30R. As in the first embodiment, the opening 23R and the color filter layer 12 do not overlap with each other in a plan view and display black. However, in the first discrimination region 30L, the opening 23L and the color filter layer 12 overlap in plan view. Therefore, when the two-screen liquid crystal display panel 1 according to the first embodiment is viewed from the surface, light that has passed through the color filter layer 12 is emitted only from the opening 23L of the first discrimination region 30L, and the opening 23L Can be visually recognized.

Next, as a third embodiment in which the viewing direction is changed, a case where the viewing direction of two images is shifted to the right will be described with reference to FIG.
In the two-screen liquid crystal display panel 1 of the third embodiment, the light shielding filter substrate 20B is different from the light shielding filter substrate 20 shown in the first embodiment. That is, as shown in FIG. 4, the light shielding filter substrate 20B is slightly shifted to the right side with respect to the liquid crystal display substrate 10, and the light shielding filter 21
Is provided. In this case, as apparent from the comparison between FIG. 4 and FIG. 2, the viewing directions of the first and second images are both shifted to the right. In this case, the first image displayed on the left side can be visually recognized from the user sitting on the left seat from the user sitting on the right seat. The second image displayed on the right side is not easily visible.

When the viewing directions of the two images are shifted to the right as described above, when the two-screen liquid crystal display panel 1 is viewed from the front surface, the first discrimination region 30L has the first discrimination region 30L out of the first and second discrimination regions 30L and 30R. As in the first embodiment, the opening 23R and the color filter layer 12 do not overlap with each other in a plan view and display black. However, in the second discrimination region 30R, the opening 23R and the color filter layer 12 overlap in plan view. Therefore, when the two-screen liquid crystal display panel 1 according to the third embodiment is viewed from the surface, the color filter layer 12 is only from the opening 23R of the second determination region 30R.
The light that has passed through is emitted, and this opening 23R can be visually recognized.

First and second discrimination regions 30L in the first to third embodiments shown with reference to FIGS.
, 30R is summarized in FIG. As can be seen from FIG. 5, since the states of the discrimination regions 30R and 30L in the three forms are different from each other, the two-screen liquid crystal display panel 1 according to the present embodiment has the first and second discrimination regions 30L, 30L, The relative positional relationship between each sub-pixel of the liquid crystal display substrate 10 and the light-shielding filter 21 of the light-shielding filter substrate 20 can be easily understood only by visually recognizing 30R. 2 to 4 show the case where the reflector 11 is formed in the first and second discrimination regions 30L and 30R of the liquid crystal display substrate 10, the reflector 1
In this case, the first and second determination regions 23L and 23R may be visually recognized in a state where light is applied from the back side of the two-screen liquid crystal display panel 1. In addition, since the openings 23L and 23R are very fine openings, there is a possibility that a confirmation error may occur. Therefore, if both the color change of the color filter layer 12 and the change of the shapes of the openings 30L and 30R are performed, more reliable. Confirmation work can be performed. In addition, if a conventional LCD driver or FPC is not attached to a two-screen LCD panel for display, the two-screen LCD panel cannot be misused, and the driver and FPC are lost when used incorrectly. Occurred. However, if the present invention is applied, the two-screen liquid crystal display panel can be inspected alone, so that the loss of the driver and the FPC does not occur.

(Modification)
In the first embodiment, the first and second discrimination regions 30L and 30 of the liquid crystal display substrate 10 are used.
Although the case where the color filter layer 12 and the reflection plate 11 are formed on R has been described, it is also possible to form the reflection plate 11 only at the position where the color filter layer 12 is formed as shown in FIG. Even in such a configuration, the two-screen liquid crystal display panel 1 of the first embodiment described above.
It is clear that the same effect is obtained. FIG. 6 shows a modification of the second embodiment shown in FIG.

Next, a second embodiment of the present invention will be described with reference to FIGS. In this embodiment, only the configuration of the discrimination region is different from that of the first embodiment, and the other configurations are the same as those of the first embodiment. Therefore, parts having the same configuration are denoted by the same reference numerals. A description thereof will be omitted, and only different points will be described below.

In the two-screen liquid crystal display panel 2 according to the second embodiment, the two-screen liquid crystal display panel 1 according to the first embodiment has a plurality of discriminating areas corresponding to the respective modes, that is, the first and second discriminating areas 30L. , 30R, but only one discriminating region 35 is provided.

In detail, the one discrimination region 35 is formed with a matrix-like opening in the light shielding filter 26 of the light shielding filter substrate 25 at a position corresponding to the discrimination region 35 of the liquid crystal display substrate 15. A color filter layer is disposed on the light shielding layer BM of the liquid crystal display substrate 11 corresponding to the position where the discrimination shape is formed. For example, FIG. 8 of the first to third embodiments described later.
In FIG. 10, color filter layers 16a, 16b, and 16c are formed corresponding to the openings 28a, 28b, and 28c of the light shielding filter 26, and these 16a, 16b, and 16c are dots that form a discrimination shape. In this way, the discriminating means is configured on the liquid crystal display substrate 11. And
The shapes formed by the color filter layers 16a, 16b, and 16c are preferably different from each other corresponding to first to third embodiments described later. Any shape may be used, but the first to third embodiments differ only in the relative positions of the sub-pixels corresponding to the first and second images of the liquid crystal display substrate 15 and the light shielding barrier 21. In consideration of the above, it is preferably an arrow shape corresponding to the shift direction of the light shielding barrier 21.

In addition, a light shielding barrier 26 is formed at a position corresponding to the discrimination region 35 of the light shielding barrier substrate 25, and the three color filter layers 16a and 16 described above are formed on the light shielding barrier 26.
Only one of b and 16c is provided with openings 28a, 28b, and 28c that overlap in plan view.

In the two-screen liquid crystal display panel 2 having the above configuration, the state of the discrimination area 35 when the viewing directions of the first and second images are changed will be described in detail below.

First, in the two-screen liquid crystal display panel 2 as the first aspect shown in FIG.
Is set at an equal angle. In this case, one of the three openings 28a, 28b, 28c formed in the light shielding barrier substrate 25 and one of the three color filter layers 16a, 16b, 16c formed in the liquid crystal display substrate 15 are used. Color filter layers 16a
Is overlapping. Accordingly, when the discrimination area 35 of the two-screen liquid crystal display panel 2 is viewed from the surface of the two-screen liquid crystal display panel 2, the color filter layer 16a of dots formed in a predetermined shape, for example, a rectangular shape, can be visually recognized through the opening 28a. It becomes like this. In this state, the openings 28b and 28c are shielded from light by the light shielding layer BM, and a simple black display is obtained.

Next, as a second mode in which the viewing direction is changed, a case where the viewing direction of two images is shifted to the left will be described with reference to FIG.
In the two-screen liquid crystal display panel 2 of the second embodiment, the light shielding filter substrate 25A is different from the light shielding filter substrate 25 shown in the first embodiment. That is, as shown in FIG. 9, the light shielding filter substrate 25A is located at a position slightly shifted to the left with respect to the liquid crystal display substrate 15.
Is provided. In this case, as apparent from the comparison between FIG. 9 and FIG. 8, the viewing directions of the first and second images are both shifted to the left.

Thus, when the viewing direction of the two images is shifted to the left, one of the three openings 28a, 28b, 28c formed in the light shielding barrier substrate 25A and the three formed in the liquid crystal display substrate 15 One of the color filter layers 16a, 16b, and 16c overlaps with the color filter layer 16b. Accordingly, the discrimination area 35 of the two-screen liquid crystal display panel 2
Is visible from the surface of the two-screen liquid crystal display panel 2, the color filter layer 16b of dots formed in a predetermined shape, for example, an arrow shape indicating the left direction, can be visually recognized through the opening 28b. In this state, the openings 28a and 28c are shielded from light by the light shielding layer BM.
It is simply black display.

Next, as a third mode in which the viewing direction is changed, a case where the viewing direction of two images is shifted to the right will be described with reference to FIG.
In the two-screen liquid crystal display panel 2 of the third embodiment, the light shielding filter substrate 25B is different from the light shielding filter substrate 25 shown in the first embodiment. That is, the light shielding filter substrate 25B is configured as shown in FIG.
As shown in FIG. 4, the light shielding filter 2 is positioned slightly shifted to the right side with respect to the liquid crystal display substrate 15.
6 is provided. In this case, as apparent from the comparison between FIG. 10 and FIG. 8, the viewing directions of the first and second images are both shifted to the right.

Thus, when the viewing direction of the two images is shifted to the right, one of the three openings 28a, 28b, and 28c formed in the light-shielding barrier substrate 25B and the three openings formed in the liquid crystal display substrate 15 are displayed. One of the color filter layers 16a, 16b, and 16c overlaps with the color filter layer 16c. Accordingly, the discrimination area 35 of the two-screen liquid crystal display panel 2
Is visible from the surface of the two-screen liquid crystal display panel 2, the color filter layer 16c of dots formed in a predetermined shape, for example, an arrow shape indicating the right direction, can be visually recognized through the opening 28c. In this state, the openings 28a and 28b are shielded from light by the light shielding layer BM.
It is simply black display.

The situation of the discrimination area 35 in the first to third embodiments shown with reference to FIGS.
It is summarized in. As can be seen from FIG. 11, since the states of the discrimination regions 35 in the three forms are different from each other, the two-screen liquid crystal display panel 2 according to the present embodiment can easily display a liquid crystal display only by visually recognizing the discrimination region 35 from the surface. Each sub-pixel of the substrate 15 and the light shielding filter substrate 25
The relative positional relationship with the light shielding filter 26 can be understood.

Note that the discriminating area 35 of the two-screen liquid crystal display panel 2 according to the second embodiment does not include the reflector 11 or the like unlike the two-screen liquid crystal display panel 1 of the first embodiment. Visual confirmation is performed by irradiating external light from the back side. Accordingly, the backlight BL that blocks light is not provided on the back side of the discrimination region 35. However, in the above embodiment, the color filter layers 16a, 16b, and 16c are used as the discriminating means. However, instead of this, a reflecting plate may be provided. In this case, the backlight BL is extended to the back of the discrimination area. There is no problem even if it is provided.
