Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal display. [Prior Art] At present, there are many application markets for liquid crystal displays, including communication, handheld mobile devices, automotive liquid crystal display screens, monitors, notebook computers, and personal computers, which will replace a large number of conventional cathodes in the foreseeable future. Line tube (Cathode Ray Tube; CRT) screen. At present, most liquid crystal displays have a black matrix layer in the liquid crystal panel to prevent light emitted from the backlight module from leaking from the edge. However, since the black matrix layer has a limited area and is far away from the light source, some large angles of light will pass through the liquid crystal panel and enter the human eye, causing light leakage problems. In particular, for liquid crystal displays used in notebook computers, the problem of light leakage is particularly serious because the light emitted by the light source is reflected by the side retaining walls beyond the shielding range of the black matrix layer. SUMMARY OF THE INVENTION Accordingly, it is an aspect of the present invention to provide a liquid crystal display having a light shielding layer disposed on a second polarizer thereof to block large angle light rays directly or indirectly incident from a light source. According to an embodiment of the present invention, a liquid crystal display includes a backlight module, a liquid crystal panel, and a light shielding layer. The liquid crystal panel is disposed on the light emitting side of the backlight module, and the liquid crystal panel comprises a first polarizer, a pair of substrates, a liquid crystal layer and a 201227065 second polarizer. One of the pair of substrates is disposed between the first polarizer and the backlight module. The liquid crystal layer is disposed between the pair of substrates described above. The second polarizer is disposed between the substrate and the backlight module, and the second polarizer includes a first surface facing the backlight module. The light shielding layer is disposed on the first surface. Another aspect of the present invention is to provide a liquid crystal display in which a light shielding film is interposed between a liquid crystal panel and a backlight module, thereby blocking large angle light rays directly or indirectly incident from the light source. According to another embodiment of the present invention, a liquid crystal display includes a backlight Φ module, a liquid crystal panel, and a light shielding film. The liquid crystal panel is disposed on the light emitting side of the backlight module, and the liquid crystal panel comprises a first polarizer, a pair of substrates, a liquid crystal layer and a second polarizer. One of the pair of substrates is disposed between the first polarizer and the backlight module. The liquid crystal layer is disposed between the pair of substrates described above. The second polarizer is disposed between the substrate and the backlight module. The light shielding film is sandwiched between the liquid crystal panel and the backlight module, and the light shielding film comprises a light transmitting area and a light shielding area. The projection of the light transmissive area on the liquid crystal panel at least partially overlaps or completely overlaps the display area of the liquid crystal panel. The light shielding area is adjacent to at least one side of the light transmitting area. Φ Compared with the prior art, the distance between the light shielding layer or the light shielding film of the above embodiment of the present invention and the light source is closer than that of the black matrix layer, so that a large angle of light can be effectively shielded or attenuated under a limited area. To solve the problem caused by light leakage. [Embodiment] The embodiments of the present invention are disclosed in the following drawings, and for the sake of clarity, the details of the invention will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. 201227065 In other words, in some embodiments of the present invention, these practical details are not necessary. In addition, some conventional structures and components will be drawn in a simple schematic manner in the drawings for the sake of simplifying the drawing. Show it. Fig. 1 is a cross-sectional view showing a liquid crystal display according to an embodiment of the present invention. As shown in the figure, a liquid crystal display includes a backlight module 1A, a liquid crystal panel 200, and a light shielding layer 300. The liquid crystal panel 2 is disposed on the light emitting side of the backlight module 100, and the liquid crystal panel 200 includes a pair of substrates 210, a first polarizer 220, a liquid crystal layer 240, and a second polarizer 23A. The substrate 21 is disposed between the first polarizer 220 and the backlight module 100. The liquid crystal layer 240 is disposed between the pair of substrates 210 described above. The second polarizer 23 is disposed between the substrate 210 and the backlight module 100, and the second polarizer 23 includes a first surface 232 facing the backlight module 100. The light shielding layer 300 is disposed on the first surface 232. Since the light shielding layer 3 of the above embodiment of the present invention is disposed on the first surface 232 ′, the distance between the light shielding layer 300 and the light source 12 背光 of the backlight module 1 为 is closer than that of the black matrix layer 250, and thus With the black matrix layer 25 〇, the ru-shi layer 300 will be more able to effectively shield or attenuate large angles of light under a limited area to solve the problem caused by light leakage. Referring to Fig. 1, a backlight module 1A of the present embodiment includes a light guide plate 110, a light source 120, and a bezel 130. The light source 12 is located on the light-in side of the light guide plate ιι. The plastic frame 130 houses the light guide plate 11 and the light source 120. In addition, if the actual situation requires 'the manufacturer can also stack a plurality of optical films 140 on the light guide plate 110, for example, the first picture is calculated from the light guide plate 11 and the lower expansion sheet 142 is sequentially stacked from bottom to top. Brightening film 144 and upper diffusion sheet 146. 2 is a bottom view of the second polarizer 230 of FIG. 1. As shown in FIG. 201227065, the light shielding layer 300 of the present embodiment may cover at least one side of the first surface 232. In this embodiment, the manufacturer may select the side of the first surface 232 to select the side of the nearest light source 120 to provide the light shielding layer 300 to effectively shield or attenuate the large angle light directly or indirectly from the light source 120. . Please refer to Figure 1. In some cases, light may pass through the gap between the light-shielding layer 3 and the inner wall of the frame 13 to cause light leakage. In order to avoid this problem, the second polarizer 230 of the present embodiment can be attached to the inner wall of the frame 130 to ensure that there is no gap between the light shielding layer 3 and the inner wall of the frame 13 to allow light to pass through to cause light leakage. Of course, the manufacturer may also choose to design the first polarizer 230 not to be aligned with the inner wall of the bezel 130, as a result of other practical conditions. In addition, in some cases, the process tolerance may cause the light shielding layer 300 to cover the edge of the first surface 232, so that even if the second polarizer 230 is attached to the inner wall of the plastic frame 130, the light can still pass through the first The edges of the two polarizers 2 cause light leakage. In order to avoid this problem, the manufacturer may choose to extend the light shielding layer 300 to the second polarizer 23 〇 adjacent to the side of the light source 12 ( (as shown in FIG. 3) to ensure that the light shielding layer 3 〇〇 covers the first The edge of face 232. Although FIG. 2 depicts the light-shielding layer 3A as covering only the first surface 232, it does not limit the present invention. In fact, the present invention is a person having ordinary knowledge in the technical field, and should be flexibly selected to cover either side of the first surface 232, any two sides, two sides or even All sides (as shown in Figure 4). Returning to Fig. 1, one of the substrates 21 of the present embodiment is a color 201227065 filter substrate 212' and the other is an array substrate 214. The color filter substrate 212 is disposed opposite to the array substrate 214. The liquid crystal layer 240 and the black matrix layer 250 are interposed between the color filter substrate 212 and the array substrate 214. The array substrate 214 described above is practically divided into a display area 215 (area where the thin film transistor array is located) and a non-display area 216 (area where the peripheral circuits are located). In order to prevent the visible range of the liquid crystal display from becoming small due to the arrangement of the light shielding layer 300, the projection of the light shielding layer 300 of the present embodiment on the array substrate 214 may completely overlap the non-display area 216 of the array substrate 214. Of course, φ may only partially overlap the non-display area 216 of the array substrate 214 if the actual situation allows the projection of the light-shielding layer 300 on the array substrate 214. The light shielding layer 300 of the present embodiment may be an opaque paint printed on the first surface 232 to surely shield light incident directly or indirectly by the light source 120. Of course, if the function of the light shielding layer 300 is only to attenuate the light directly or indirectly incident by the light source 120, the light shielding layer 300 may also be a translucent coating printed on the first surface 232. In the present embodiment, the method of printing the light shielding layer 300 φ on the first surface 232 may include the following steps: (1) tearing off the release film coated on the first surface 232. (2) printing on the first surface 232 (more specifically, the surface of the Tri-acetyl cellulose (TAC) layer of the second polarizer 230) by screen-printing A coating or a semi-transparent coating is used as the light shielding layer 300. (3) The degree of adhesion of the light shielding layer 300 to the first surface 232 is tested with a tape. (4) If the degree of adhesion of the light shielding layer 300 to the first surface 232 is in accordance with the requirements of 201227065, the release film is overlaid on the first surface 232. The material of the release film may be polyethylene terephthalate (PET). It should be understood that the above-described manufacturing method of the light-shielding layer 300 is merely illustrative, and is not intended to limit the present invention. The person skilled in the art to which the present invention pertains should elastically select the manufacturing method of the light-shielding layer 300 as needed. In addition to shielding or attenuating a large angle of light with the light shielding layer 300, the following embodiment of the present invention will sandwich a light shielding film 400 ′ between the liquid crystal panel 200 and the backlight module 1 借此 to block the light source 120 Large angle light that is injected directly or indirectly. It should be understood that the contents which have been described in the above embodiments in the following description will not be repeated, and only the technical contents of the portion of the light-shielding film 400 will be supplemented. Fig. 5 is a cross-sectional view showing a liquid crystal display according to still another embodiment of the present invention. As shown in the figure, the present embodiment does not print the light-shielding layer 300 on the second polarizer 23, but is replaced by a separate light-shielding film 4'. The light-shielding film 400 is interposed between the liquid crystal panel 2 and the backlight module 1 and the light-shielding film 400 includes a light-transmitting region 410 and a light-shielding region 420. The projection of the light-transmitting region 410 on the liquid crystal panel 200 at least partially overlaps or completely overlaps the display region of the liquid crystal panel 200. The light shielding region 420 is adjacent to at least one side of the light transmitting region 410. Since the light shielding area 420 of the above embodiment of the present invention is disposed between the liquid crystal panel 200 and the backlight module 1〇〇, the distance between the light shielding area 42〇 and the light source ι2〇 is closer than that of the black matrix layer 25〇, so Compared with the black matrix layer 250, the light shielding region 420 will be more capable of effectively shielding or attenuating large angles of light under a limited area, thereby solving the problem caused by light leakage. In the present embodiment, the light-shielding film 400 is directly sandwiched between the optical film 14A and the second polarizer 23A on the outermost side of the backlight module 100. Taking Fig. 5 as an example, the light-shielding film 400 of Fig. 5 is directly sandwiched between the upper diffusion sheet 146 and the second polarizer 230, and is in contact with both. At the time of assembly, the manufacturer may first stack the light-shielding film 4 on the upper diffusion sheet 146, and then stack the liquid crystal panel 200 on the light-shielding film 400. The projection of the light transmissive region 410 on the array substrate 214 of FIG. 5 at least partially overlaps or completely overlaps the display region 215 of the array substrate 214. The projection of the blackout region 420 of the fifth φ image on the array substrate 214 may at least partially overlap or completely overlap the non-display region 216 of the array substrate 214. That is, if we divide the liquid crystal panel 200 into a display area and a non-display area, the projection of the light transmissive area 410 on the liquid crystal panel 200 may at least partially overlap or completely overlap the display area. The projection of the light-shielding region 420 on the liquid crystal panel 200 may at least partially overlap or completely overlap the non-display area. This configuration is to allow the setting of the light-shielding area 420 to be blocked as much as possible from the display area, affecting the visible range of the liquid crystal display. φ Fig. 6 is a bottom view of the light shielding film 400 of Fig. 5. As shown in the figure, the light shielding region 420 of the present embodiment covers at least one side of the light shielding film 400. In the present embodiment, the manufacturer can select the light-shielding region 420 on the side of the light-shielding film 400 that is closest to the light source 丨20 to effectively shield or attenuate the large angle directly or indirectly from the light source 120. Light. Please refer to Figure 5. In some cases, light may cross the gap between the opaque film 400 and the inner wall of the frame 130, causing light leakage problems. In order to avoid this problem, the light-shielding film 400 of the present embodiment can be attached to the inner wall of the frame of the glue 201227065 to ensure that there is no gap between the light-shielding film 4 〇〇 and the inner wall of the frame i3 能够 to allow light to pass through to cause light leakage. § However, after the other actual conditions are weighed, the manufacturer may also choose to design the light-shielding film 400 not to be aligned with the inner wall of the frame. Although FIG. 6 illustrates the light-shielding region 420 as being adjacent only to at least one side of the light-transmitting region 410, this does not limit the present invention. In fact, those having ordinary knowledge in the technical field of the present invention should flexibly select the light-shielding region 420 to be adjacent to either side of the light-transmitting region 410, any two sides of the φ side, any three sides, or even Surrounding the light transmissive area 410 (as shown in FIG. 7). The light-shielding region 420 of the present embodiment can be printed with an opaque paint to surely shield the light directly or indirectly from the light source 120. Of course, if the function of the opaque region 420 is only to attenuate the light incident directly or indirectly by the light source 120, only the semi-transparent paint may be printed on the opaque region 420. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. Fan φ is subject to the definition of the patent application scope attached.
