That is, the user can view the angle P1 and The viewing angle P2 respectively sees different images. However, the light rays 13 from the second pixel region 112b interfere with the light L1 originally emitted from the first pixel region 112a, thereby degrading the display quality, and vice versa. In detail, FIG. 1B is a schematic diagram of optical simulation of a conventional dual-view liquid crystal panel. Referring to FIG. 1B, when viewing the pupil plane from the first pixel region 112a at the position of the viewing angle P1, at a larger viewing angle (about -60 degrees) In the direction of the following), there will be light from the second pixel area 112b Intensity; similarly, when viewing the pupil plane from the second pixel region mb at the position of the viewing angle P2, there is a light intensity from the first pixel region U2a in a direction of a larger viewing angle (about 60 degrees or more).

The material of the common electrode 260 is, for example, indium tin oxide (ITO), indium oxide (IZO) or aluminum zinc oxide (AZO). Thus, the production of the color filter substrate 2 is substantially completed. In summary, the color filter substrate 200 having the lateral light-shielding structure 242 can be easily formed by the steps as shown in Figs. 2A to 2H. In particular, as shown in FIG. 2D, the step of forming the recess 230a by patterning the first cladding layer 23 is such that the second light-shielding material 240a for forming the black matrix layer 244 can be simultaneously used to form the lateral direction.

The color filter substrate is similar to the above-described color filter substrate 200, and the same members are designated by the same reference numerals and will not be described again. The difference between the two is that in the color filter substrate 300, a second cover layer 232 is further disposed between the first cladding layer 230 and the black matrix layer 244. The material of the second cladding layer 232 is, for example, a transparent resin. The manner of forming this second cladding layer 232 is, for example, a spin coating method.

That is, the second light-shielding material 240a for forming the black matrix layer 244 is filled into the recess 230a, thereby forming the lateral light-shielding structure 242. This manufacturing method is convenient. However, the size of the lateral light-shielding structure 242 formed is liable to cause a non-uniform condition, which affects the subsequent shading effect. Therefore, in the second embodiment, the lateral light shielding structure 242 and the black matrix 244 are different film layers. That is, the lateral light blocking structure 242 is first formed in the first cladding layer 230. Thereafter, a second cladding layer 232 is further disposed on the first cladding layer 230, and the black matrix layer 244, the color filter layer 250, and the common electrode 260 are further formed on the second cladding layer 232. 13 ^OZ1TW 24347twf.doc/n 201028742 This production method can more precisely control the size of the lateral shading structure 242 to ensure lateral shading.

Further, since the liquid crystal panel 400 does not have a function of actively emitting light, the light source 430 can be disposed on one side of the liquid crystal panel 4''. For example, the light source 43A may be disposed on the side of the active device array substrate 41 of the liquid crystal panel 400, and the light source 430 may be a cold cathode fluorescent lamp, a light emitting diode array light source' or a cold cathode fluorescent flat lamp. Continuing to refer to FIG. 4, in the liquid crystal panel 400, the opaque grid layer 220 is adapted to allow a plurality of image lights to be emitted in two viewing directions to display two image planes. Therefore, the user can see the display screen of different contents at the angle of view P1 and the angle of view P2, respectively. In particular, since the color filter substrate 4 has the lateral light-shielding structure 242, it is possible to prevent the user from seeing the light from the other face] L4 when viewed from the viewing angle P2. Thereby, the light from the adjacent sub-halogen regions 250a can be prevented from interfering with each other, and the display product 14 2〇1〇28742zitw 24347twf.doc/n can be effectively improved. It should be noted that the length d of the lateral light shielding structure 242 is 1/3 to 1/2 of the thickness D of the first partial layer 230.

Inside, and with the appropriate spacing of the shading grid layer 220, three display pupils are provided. The opaque grid layer 220 allows a plurality of image lights to be emitted in three viewing directions to display three image frames. Therefore, the user can see the display faces of different contents at the viewing angle pl, the viewing angle P2, and the viewing angle P3, respectively. Similarly, the lateral light-shielding structure 242 prevents the light from the adjacent sub-halogen regions 25A from interfering with each other, and can effectively improve the display quality.
