2. Description of the Related Art As a current color liquid crystal display device, an active matrix type color liquid crystal display device is predominant because there is no crosstalk between adjacent pixels and a good display image can be realized.

have.

The counter substrate 58, which is arranged so as to face the array substrate 57, has a substrate 59 which is also formed of a transparent glass material, and is provided on the face of the substrate 59 which faces the array substrate 57. Is blue composed of acrylic material,
A plurality of colored layers 60B, 60G, and 60R that form the green and red three-color color filters 60 are provided.
A transparent counter electrode 61 made of ITO or the like is provided on the surfaces of B, 60G, and 60R. An alignment film 62 made of polyimide or the like is provided on the counter electrode 61, and a frame portion 63 formed of a black light-shielding film is provided on the outer peripheral portion of the display area. The non-display area is covered by 63.

Further, silver paste (not shown) or the like is arranged in the peripheral portion of the screen as an electrode transfer material for applying a voltage from the array substrate 57 to the counter substrate 58, and the electrode transfer material opposes the array substrate 57. The boards 58 are electrically connected to each other.

Between the array substrate 57 and the counter substrate 58,
The gap is defined by a spacer 64 interposed between the two substrates 57 and 58. The two substrates 57 and 58 are opposed to each other with a predetermined gap, and the peripheral portions thereof are heat- or ultraviolet-curing acrylic. They are adhered to each other via a sealing material 65 composed of a system or epoxy adhesive, and a liquid crystal member 66 is sealed in this gap to form a liquid crystal panel 67.

The spacer 64 is a color filter 60.
Since the same material as the colored layers 60B, 60G, and 60R constituting the
At the time of forming B, 60G, and 60R, the spacer 64 is simultaneously formed by using the same material by a photolithography method, thereby reducing the number of steps.

Further, polarizing plates 68 are attached to both outer surfaces of the liquid crystal panel 67 with an adhesive, and a backlight or a reflection plate (if necessary) is provided outside the polarizing plates 68 on the array substrate 57 side. (Not shown) and the like are arranged to form a color liquid crystal display device.

In the color liquid crystal display device configured as described above, for example, a backlight serving as a light source is turned on, and the TFT 5
The pixel electrodes 55 are switching-controlled by driving the pixel electrodes 55, and each pixel electrode 55 is controlled by the potential difference between the voltage of the pixel electrode 55 and the voltage supplied to the opposing electrode 61.
A predetermined color image is displayed by controlling the upper liquid crystal member 66 to function as an optical shutter.

The laminated spacer 64 constituting this color liquid crystal display device is also formed at the time of forming the pattern of the color filter 60, but when the second and third color materials are applied, it is formed on the substrate 59. Leveling when the colored layers 60G and 60B are applied at each installation location where each spacer 64 is formed because the coating surface is uneven due to the colored layer already formed on the substrate, for example, the red colored layer 60R. Since the thickness of the uppermost layer or the intermediate layer varies depending on the installation location, the height of the formed spacer 64 varies depending on the installation location, as shown in FIG. The height of the spacer 64 varies.

That is, the first layer of the spacer 64 is the substrate 59.
The coloring layer 6 is formed by applying the first color material on the top and patterning.
0R is formed, but the second color coloring material is used as the first color coloring layer 6
0R coating and patterning to form the second layer projections 69 constituting the spacer 64 on the first colored layer 60R, then coating the third color material and then patterning. By further forming the protrusion 70 on the protrusion 69, the laminated spacer 64 is formed. At this time, the height of the bottom surface on both sides of the protrusion 69 or 70 becomes large depending on the place where the spacer 64 is formed, that is, whether the adjacent portions are the second or third colored layers 60G and 60B. However, even if the protrusions 69 and 70 are sequentially laminated by patterning the second color or the third color, the colorant applied for this purpose is greatly pulled in the direction of the large step. The height is inevitably lower than that of the spacer 64 formed in a small area.

Factors that cause variations in the height of the spacers 64 are, in addition to the problem of the leveling property when applying the intermediate layer and the uppermost layer of the spacers 64, the size of the lamination pattern and the lamination. The thickness of the lower layer pattern is considered.

As described above, when the gap of the display panel 67 is defined by the laminated spacer 64, the display panel 6
The gap of No. 7 is 4.9 ± 0.5 μm and the uniformity is low, and a display defect due to the gap unevenness occurs.

As a form of the spacer 64 used in the liquid crystal display device, such a laminated type spacer 64 is used.
Besides, a single-layer type spacer is also known. As shown in FIG. 7, this single-layer type spacer is also formed by using this frame material at the same time when the frame portion 63 is formed on the surface of the counter electrode 61 of the counter substrate 58. ing.
The same components as those in FIG. 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

In such a single-layer type spacer 71, for example, the variation in the film thickness when the frame material is applied by using the spinner directly occurs as the variation in the height of the spacer 71. That is, the centrifugal force is generated by the rotation during spin coating, and the film thickness of the central portion of the substrate 59 is large and the film thickness of the peripheral portion is thin. Therefore, as shown in FIG. Has a high height and tends to be low in the surrounding area. Therefore, even in the case of this single-layer type spacer 71, the height of the spacer 71 varies. Actually, this single layer type spacer 7
When the gap of the liquid crystal panel 67 using No. 1 was measured, it was 5.1 ± 0.45 μm and the uniformity was low, and the gap at the central portion of the substrate 59 was 5.5 μm, which was worse. Due to this nonuniformity of the gap, display defects due to unevenness in the gap have occurred.

[0015]

As described above, in the area having the color filter 60 pattern such as the display area,
Colored layers 60R, 60 forming the color filter 60
When the laminated spacer 64 having a structure in which the materials of G and 60B are laminated is manufactured, the height of each spacer 64 is determined depending on the place where each spacer 64 is formed. Therefore, the uniformity of the distance between the array substrate 57 and the counter substrate 58 may be impaired. Such a phenomenon is particularly remarkable when a color filter 60 material having a high leveling property is used.

The single layer type spacer 71 is also formed by spin coating, so that centrifugal force is generated and the substrate 59
The height of the central portion is higher than that of the peripheral portion, and the height of the spacers 71 also varies, so that it is impossible to obtain the spacers 71 exhibiting a uniform height distribution.

These spacers 64 and 71 are formed by the liquid crystal member 6.
Since the thickness of the liquid crystal member 6 is regulated, the height of each of the spacers 64 or 71 varies, so that the liquid crystal member 6
This is a factor that causes a fatal defect such as thickness unevenness of No. 6.

The present invention has been made in response to such a problem, and by using mixed spacers such as a laminated spacer and a single-layer spacer which cause different height variations, they are mixed. It is an object of the present invention to provide a color liquid crystal display device having a good display quality and a method for manufacturing the color liquid crystal display device in which variations in the spacer group are suppressed.

The spacer and the single-layer type spacer formed of a single material are mixed to form a spacer group.

Further, an array substrate having a switching element arranged on one plane of the substrate and a pixel electrode connected to the switching element, and a counter electrode arranged so as to face the array substrate and facing the opposite surface. Defining a gap between the array substrate and the counter substrate, and a color filter formed of a colored layer of three colors of blue, green, and red formed on any of the facing surfaces between the counter substrate and the array substrate.
