Description
Technical field
The present invention relates to a kind of multizone homeotropic alignment (multi-domain vertical alignment, MVA) LCD panel, specifically, relate to a kind of multizone homeotropic alignment liquid crystal display board of avoiding arranging protrusion (alignment protrusion) edge generation light leakage phenomena.
Background technology
LCD widely is applied in various electronic product, as mobile phone, PDA(Personal Digital Assistant) and mobile computer (notebook) etc., and fast development along with large scale flat-panel screens market, LCD with compact characteristic is being played the part of considerable role especially, becomes the market mainstream and replace the cathode ray tube (CRT) display gradually.Yet LCD becomes developmental restrictive condition because the visual angle is wide inadequately, and therefore a kind of multizone homeotropic alignment liquid crystal display board that increases the visual angle just arises at the historic moment.
Please refer to Fig. 1, Fig. 1 is the diagrammatic cross-section of the multizone homeotropic alignment liquid crystal display board 10 of a prior art.As shown in Figure 1, the multizone homeotropic alignment liquid crystal display board 10 of prior art comprises a upper substrate 12, an infrabasal plate 14, be filled in a layer of liquid crystal molecule 16 between upper substrate 12 and the infrabasal plate 14, be located at upper substrate 12 in the face of the lip-deep color filter layers 18 of infrabasal plate 14, be located at a transparency conducting layer 20 between color filter layers 18 and the infrabasal plate 14, be located at the lip-deep first order protrusion 22 of transparency conducting layer 20 in the face of infrabasal plate 14, and be located at the lip-deep second order protrusion 24 that infrabasal plate 14 is faced upper substrate 12.Wherein, color filter layers 18 comprises a plurality of redness, green and blue color filter, is used for filtering light, so that LCD panel produces gay colours, and a sub-pixel of the equal corresponding LCD panel of each optical filter (sub pixel) district.
In addition, the multizone homeotropic alignment liquid crystal display board 10 of prior art includes a plurality of black matrix"s (black matrix) 26 in addition, be located between the optical filter of any two different colours, be used for preventing that the light in each sub-pixel area is incident to adjacent sub-pixel area, to promote the color contrast of multizone homeotropic alignment liquid crystal display board 10.And be arranged at first order protrusion 22 and second order protrusion 24 in the multizone homeotropic alignment liquid crystal display board 10, then be used for same sub-pixel area is separated into several zones, and make the liquid crystal molecule in each zone be different specific directions arrangements and rotation, with the visual angle of effective increase multizone homeotropic alignment liquid crystal display board 10.
As mentioned above, though the multizone homeotropic alignment liquid crystal display board of prior art has wider visual angle, yet make the part liquid crystal molecule not apply the slight rotation of meeting generation under the voltage condition owing to arrange protrusion, especially be positioned at and arrange near the liquid crystal molecule of protrusion, therefore can cause LCD panel to produce light leakage phenomena and reduce the contrast of LCD, and then influence the liquid crystal display displays effect.For instance, when a certain pixel region need show an all black, the redness of this pixel region, green and blue subpixels should be complete dark state in theory, and just can't show desirable all black when the light leak situation takes place, thereby cause contrast effect not good.Or when the color of a certain pixel region demonstration only needed to use the combination of redness and green, the light leak in blue subpixels district just can cause this pixel region can't show required color, thereby influences the liquid crystal display displays effect.
Summary of the invention
Therefore, (multi-domain vertical alignment, MVA) LCD panel is to avoid the shortcoming of above-mentioned prior art to the object of the present invention is to provide a kind of multizone homeotropic alignment with light-shielding pattern.
