Second embodiment
Fig. 3 is the diagrammatic cross-section of multi-domain vertical aligning display panel of the present invention.Please refer to Fig. 3, at first, provide a colored optical filtering substrates 200 and a multidomain vertical alignment type active component array base board 300.Colored optical filtering substrates 200 is exposed among first embodiment in detail, does not add to give unnecessary details at this.Then, between colored optical filtering substrates 200 and multidomain vertical alignment type active component array base board 300, form a liquid crystal layer 400.So just, can produce multi-domain vertical aligning display panel 500 of the present invention.
Multi-domain vertical aligning display panel 500 as shown in Figure 3 is made of with liquid crystal layer 400 colored optical filtering substrates 200, multidomain vertical alignment type active component array base board 300.In detail, above-mentioned multidomain vertical alignment type active component array base board 300 comprises a substrate 302 and the pixel cell 304 of a plurality of array configurations on substrate 302.Each pixel cell 304 comprises at least one active member 306 and one and the pixel electrode 308 that electrically connects of active member 306.Certainly, have in the affiliated technical field and know that usually the knowledgeable should know that the number of active member 306 answers the design of the plain unit 304 of video and decide, the pixel cell that for example has precharge (Pre-charge) design is the plural active member 306 of needs just.Painstakingly do not limit to the number of active member 306 in each pixel cell 304 at this.
For instance, active member 306 can be bottom-gate (bottom gate) structure.Active member 306 mainly comprises a grid 306g, a gate insulation layer 306i, a channel layer 306c, one source pole 306s and a drain electrode 306d.Wherein, grid 306g is disposed on the substrate 302, and gate insulation layer 306i cover grid 306g.In addition, channel layer 306c is disposed on the gate insulation layer 306i of grid 306g top.Above-mentioned source electrode 306s and drain electrode 306d then are disposed at the both sides on the channel layer 306c respectively.
In addition, active member 306 can cover by protected layer 305, and has a contact window H in the protective seam 305, to expose drain electrode 306d.On the practice, above-mentioned pixel electrode 308 can be by contact window H, and electrically connects with active member 306.Here be noted that and have a plurality of slit S1 on the pixel electrode 308.Slit S1 can influence Electric Field Distribution and make and be multi-direction arrangement after liquid crystal molecule is driven in the liquid crystal layer 400, so that display frame has wider angle of visibility.
Patterning colored light filter membrane layer 204 that it should be noted that colored optical filtering substrates 200 of the present invention has a plurality of grooves 205, and that common electrode layer 206 can be with groove 205 is surperficial conformal.In other words, the common electrode layer 206 that is positioned at groove 205 places also can influence Electric Field Distribution, is multi-direction arrangement and make effectively after liquid crystal molecule is driven in the liquid crystal layer 400.Specifically, shade 208 can fill up groove 205.As shown in Figure 3, the surface of the surface of common electrode layer 206 and shade 208 in fact can be on same extended surface.
If the multi-domain vertical aligning display panel of setting with the black picture (normally black) of normality 500 is that example explains, because shade 208 can fill up groove 205, therefore the liquid crystal molecule in the liquid crystal layer 400 does not have bad tilt state before being driven, and then can effectively avoid abnormal light leakage phenomena.On the other hand, the contrast of display frame also can effectively promote.
In sum, colored optical filtering substrates of the present invention is owing to being disposed at shade on the common electrode layer, to fill up groove.Therefore, the liquid crystal layer between colored optical filtering substrates and multidomain vertical alignment type active component array base board can have good initial arrangement state.So multi-domain vertical aligning display panel of the present invention can effectively prevent abnormal light leakage phenomena, and the contrast of lifting display frame, and then good display quality can be arranged.In addition, the manufacture method of colored optical filtering substrates of the present invention can effectively reduce photomask processing procedures, and then can reduce manufacturing cost.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
