Embodiment
Hereinafter with reference to relevant drawings, illustrate that wherein same components is represented with same numeral according to the wild display device of a kind of double vision of the preferred embodiment of the present invention, bilateral-visual display panel and manufacture method thereof.
First embodiment
With reference to shown in Figure 2, the manufacture method of bilateral-visual display panel of the present invention comprises that step S1 is to step S3.Simultaneously with reference to shown in Fig. 2 and Fig. 3 A, step S1 is for being arranged at thin film transistor base plate 211 side of colored filter substrate 212, wherein thin film transistor base plate 211 has first surface T1 and second surface T2, colored filter substrate 212 has first surface C1 and second surface C2, the first surface T1 of thin film transistor base plate 211 and the first surface C1 of colored filter substrate 212 are oppositely arranged, and form liquid crystal chamber cave O between thin film transistor base plate 211 and the colored filter substrate 212.
Thin film transistor base plate 211 has substrate 211a, sets gradually driven unit layer 211b and pixel electrode layer 211c on it.Wherein, substrate 211a for example is a glass substrate, and driven unit layer 211b has a plurality of thin film transistor (TFT) (not shown)s, and thin film transistor (TFT) for example is amorphous silicon film transistor or low-temperature polysilicon film transistor.The material of pixel electrode layer 211c for example be tin indium oxide (IndiumTin Oxide, ITO).
Then, with reference to shown in Fig. 3 B.Earlier the second surface C2 to colored filter substrate 212 grinds (not shown), is example with the substrate 212a of thinning colored filter substrate 212, is 300um by the 630um attenuate for example.Wherein, lapping mode for example is mechanical lapping or chemical grinding.Then, utilize etching mode simultaneously thinning thin film transistor base plate 211 and colored filter substrate 212 again so that the thickness H of substrate 212a again attenuate reach a preset thickness, be 90um in this preset thickness.Wherein, etching mode is selected from dry-etching, Wet-type etching and the group that combination constituted thereof at least a.
With reference to shown in Fig. 2 and Fig. 3 C, step S2 is for forming liquid crystal layer 213 simultaneously.Wherein, the step that forms liquid crystal layer 213 can comprise that also seeing through liquid crystal chamber cave O injects liquid crystal material, so that form liquid crystal layer 213 between thin film transistor base plate 211 and the colored filter substrate 212, and encapsulated liquid crystals chamber cave O.
At last, simultaneously with reference to shown in Fig. 2 and Fig. 3 D, step S3 is for to be arranged at shielding element 214 on the second surface C2 of colored filter substrate 212.Shielding element 214 has base material 214a and light shield layer 214b (barrier).Wherein, the material of base material 214a for example is glass or high molecular polymer.And base material 214a also can utilize Polarizer to be base material, and uses as polarizing layer, not only operation can be integrated thus, also can reduce material cost.In addition, the material of light shield layer 214b for example is extinction materials such as resin (resin), ferrous metal or metal oxide.
Therefore, after light L passes the G1 of group of pixel cell among the chromatic filter layer 212b and when direction d2 penetrates, can be absorbed or reflection by the material of light shield layer 214b, makes light L pass the G1 of group, only can penetrate bilateral-visual display panel 21 from direction d1.Similarly,, then can be absorbed or reflection, so light L only can penetrate bilateral-visual display panel 21 from direction d2 after passing the G2 of group by the material of light shield layer 214b if the light L that passes the G2 of group penetrates from direction d1.Therefore, when two different visual angles are watched, can see different display frame.In addition, light shield layer 214b also can absorb the light from outside incident, to improve the contrast of display frame.
In addition, earlier with reference to shown in Figure 4, the long limit m that rectangular sub-pixel R, G and B had among each pixel cell U of chromatic filter layer 212b is set to the minor face N in the face of rectangle colored filter substrate 212.And sub-pixel R, G and B are respectively red sub-pixel, green sub-pixels and blue subpixels, or are dark green sub-pixel, reddish violet sub-pixel and yellow sub-pixel.
In addition, refer again to shown in Fig. 3 D, under the situation of the distance between two visual angles, must keep the interval S (as shown in Figure 1) of about 90um between light shield layer 214b and the chromatic filter layer 212b, just can obtain best appreciation effect at about 100cm.Present embodiment then utilizes the substrate thickness H of colored filter substrate 214 as interval S, and therefore, present embodiment is about under the situation of 100cm in distance between two visual angles, can obtain best appreciation effect.In addition, the manufacturing of the colored filter substrate 212 of present embodiment can be continued to use conventional processes to reduce cost, and need not utilize other for example material such as light-transmissive resin form interval S (as shown in Figure 1), therefore can avoid the issuable variety of issue of prior art, and because of increasing the cost increase that material causes.
Second embodiment
With reference to shown in Figure 5, the difference of the bilateral-visual display panel 21 of the present embodiment and first embodiment is: in the present embodiment, the long limit m that rectangular sub-pixel R, G and B had among each pixel cell U ' of chromatic filter layer 212b ', all be set in the face of rectangle colored filter substrate 212 ' long limit M.
Then, simultaneously with reference to Fig. 4 and shown in Figure 5, for both difference is described, (long limit M) * 480 (minor face N) are that example explains with resolution 800.Wherein, 800 and 480 represent pixel cell U and the U ' quantity that both sides M, N have respectively.
