In other embodiments, first substrate 210 can be an active elements array substrates also, and second substrate 220 is colored optical filtering substrates, and the transparent electrode layer 216 that covers first substrate 210 can be a plurality of pixel electrodes.In addition, in other embodiments, first substrate 210 also can be AOC (the Array On Color Filter) substrate that chromatic filter layer 214 directly is integrated in COA (the Color Filter On Array) substrate on the active device array or active device array is integrated in color filter layers 214, at this moment, first substrate 210 can be glass substrate, plastic substrate or other suitable substrates, in other words, second substrate 220 does not comprise chromatic filter layer 214.
Please continue with reference to figure 7, homeotropic liquid crystal display panel 200 has a plurality of pixel region Pi (Fig. 7 only illustrates single pixel region Pi), and the liquid crystal molecule 232 in each pixel region Pi can be a plurality of different toppling directions by pairing strip orientation projection 240.
Specifically, each of present embodiment first strip orientation projection 240a and second strip orientation projection 240b are by alternately the link to each other strip projected parts of the continuous bending that constituted of a plurality of first orientation section 244a and a plurality of second orientation section 244b.In the present embodiment, the bearing of trend 246a of the first orientation section 244a is parallel with the first smooth penetrating shaft 252a, and the bearing of trend 246b of the second orientation section 244b is parallel with the second smooth penetrating shaft 252b.
Thus, when homeotropic liquid crystal display panel 200 display frames, be positioned near the liquid crystal molecule 232a of the first orientation section 244a, the direction 234a of its major axis can be parallel to the second smooth penetrating shaft 252b.And, being positioned near the liquid crystal molecule 232b of the second orientation section 244b, the direction 234b of its major axis can be parallel to the first smooth penetrating shaft 252a.Therefore, when homeotropic liquid crystal display panel 200 display frames, near by liquid crystal molecule 232a, 232b first orientation zone 244a and the second orientation section 244b light can be stopped by the first polaroid 250a or the second polaroid 250b, make the light leak problem, particularly the light leak problem when dark attitude achieves a solution.
Furthermore, each strip orientation projection 240 comes down to the zigzag strip projected parts of bending (zigzag) continuously, and each strip orientation projection 240 is alternately to be connected in series by a plurality of first strip orientations projection 240a and the protruding 240b of a plurality of second strip orientation.Wherein, the whole bearing of trend 242b of the whole bearing of trend 242a of first strip orientation projection 240a and second strip orientation projection 240b can have an angle theta with the first smooth penetrating shaft 252a respectively, and 0 degree＜θ＜90 degree can define four orientation field I, II, III, IV whereby in each pixel region Pi.In the present embodiment, above-mentioned angle theta is 45 degree, i.e. the whole bearing of trend 242b mutually orthogonal of the whole bearing of trend 242a of first strip orientation projection 240a and second strip orientation projection 240b.
In the present embodiment, select all strip orientation projectioies 240 are disposed on first substrate 210, and on the transparent electrode layer 224 of second substrate 220, form a plurality of orientation slit 224a corresponding to strip orientation projection 240.In addition, transparent electrode layer 224 also can have a plurality of little slits (fine slits) 224b.Little slit 224b can link to each other and be positioned at the relative both sides of orientation slit 224a respectively with pairing orientation slit 224a.
By of the configuration of strip orientation projection 240 with orientation slit 224a, can make liquid crystal molecule 232 in each pixel region Pi along four orientation field I, II, III, IV and present different alignment direction, and then make homeotropic liquid crystal display panel 200 reach wide-visual angle effect.More specifically, in one of them, the toppling direction of liquid crystal molecule 232 is roughly to be identical at orientation field I, II, III, IV; But the toppling direction of the liquid crystal molecule 232 in different alignment field I, II, III, IV is then different.See through liquid crystal molecule 232 and topple over arrangement toward a plurality of directions, the optical effect that the liquid crystal molecule 232 in different alignment field can compensate visual angle change mutually and produced, and make homeotropic liquid crystal display panel 200 can have bigger angle of visibility scope.
The correlative value of image is the ratio of bright attitude briliancy divided by dark attitude briliancy.In the above-described embodiments, bright attitude briliancy is remained unchanged and dark attitude briliancy reduces effectively.In other words, the homeotropic liquid crystal display panel of the foregoing description can have higher correlative value, and can effectively improve the problem of light leak, therefore can provide better display effect.
What deserves to be mentioned is, though the foregoing description forms projection on first substrate 210, on second substrate 220, form slit, but in fact, in other embodiments of the invention, also can be chosen on first substrate 210 with on second substrate 220 and all form projection, or form the projection and the slit of arranging in pairs or groups mutually respectively on first substrate 210 or on second substrate 220, it can reach the orientation effect of wide viewing angle equally.The visual practical situation of those skilled in the art changes the configuration mode of projection and slit, and can be in spiritual scope of the present invention the trend of projection, shape, quantity etc. be adjusted.
In sum, the present invention disposes the strip orientation projection of bending continuously in homeotropic liquid crystal display panel, the tendency that liquid crystal molecule is had topple over toward a plurality of different directions to be forming a plurality of orientations field, and makes homeotropic liquid crystal display panel reach wide-visual angle effect.In addition, this bends continuously and presents jagged strip orientation projection and be made of a plurality of orientation sections that alternately link to each other each other, and the bearing of trend of these orientation sections is parallel with two smooth penetrating shafts of two polaroids respectively.Therefore, when homeotropic liquid crystal display panel display frame, the long axis direction that is positioned near the liquid crystal molecule of orientation section can be parallel with two smooth penetrating shafts, thereby can stop effectively that light passes through, and then reduction light leak, the phenomenon of especially dark attitude light leak, and can promote the correlative value of display frame and have good display effect.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; any those of ordinary skills; without departing from the spirit and scope of the invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking appended the scope that claim defined.
