These second pixel cell 260 corresponding two the 3rd projections 243, one the 4th projection 244, one the 3rd groove 283 and two the 4th grooves 284.
The projection 241,242 of the projection 243,244 of this second pixel cell 260 and the arrangement of groove 283,284 and this first pixel cell 250 and the arrangement of groove 281,282 are roughly the same, wherein, the position corresponding relation is as follows: 243 pairs of the 3rd projections should first projection 241,244 pairs of the 4th projections should second projection 242,283 pairs of the 3rd grooves should first groove 281 and 284 pairs of the 4th grooves should second groove 282.This first pixel cell 250 is with the key distinction of this second pixel cell 260: these two the 3rd projections 243 roughly constitute and these two first sub-projection 241a V-arrangement in the same way, one the 3rd projection 243 comprises one the 3rd sub-projection 243a and two second extension 243b that extend from the 3rd sub-projection 243a two ends respectively, these two second extension 243b are parallel with sweep trace 225 with this data line 223 respectively, and two the 3rd sub-projection 243a are parallel with these two first sub-projection 241a respectively.Vertical range between the 3rd groove 283 and the 4th groove 284 is W2, and W2＞W1, and the pixel electrode width that defines this second pixel cell 260 is this vertical range W2.The groove width of the 3rd groove 283 and the 4th groove 284 all is L2, and L1=L2.

One pixel cell 229 of this multi-domain vertical alignment-type liquid crystal display panel 200 comprises first pixel cell 250 and half-pix unit 260 once, and a red filter unit of these pixel cell 229 corresponding colored filters 213, green filter unit or blue filter unit.Liquid crystal molecule in this pixel cell 229 has the orientation of eight different directions.Light beam is in the transmitance unanimity of eight directions of this pixel cell 229.Observe from all directions, light is less through the optical path difference of liquid crystal molecule, the picture effect basically identical of this multi-domain vertical alignment-type liquid crystal display panel 200, compare with four territory vertical alignment-type liquid crystal display panels 100 of prior art, this multi-domain vertical alignment-type liquid crystal display panel 200 can improve color offset phenomenon.
In addition, the part that is parallel to this sweep trace 225 of this first, second, third, fourth projection 241,242,243,244 and the main effect that is parallel to the part of this data line 223 are that liquid crystal molecule is divided in zones of different, and make the liquid crystal molecule that is close to it have certain orientation, can avoid nidus can't have certain orientation, and cause the bright attitude of this multi-domain vertical alignment-type liquid crystal display panel 200 to show the phenomenon of concealed wire at the liquid crystal molecule of the juncture area (as the juncture area of B, C) in adjacent two zones.
In like manner, second extension groove of the first extension groove 281b of this first groove 281 and second groove 282 also can avoid the bright attitude of this multi-domain vertical alignment-type liquid crystal display panel 200 to show the phenomenon of concealed wire.
Seeing also Fig. 7, is the diagrammatic cross-section of multi-domain vertical alignment-type liquid crystal display panel second embodiment of the present invention.The key distinction of the multi-domain vertical alignment-type liquid crystal display panel 200 of this multi-domain vertical alignment-type liquid crystal display panel 300 and first embodiment is: form a plurality of grooves in the public electrode 315 of this multi-domain vertical alignment-type liquid crystal display panel 300, its shape is identical with the shape and the arrangement mode of the projection 241,242,243,244 of the arrangement mode and the first embodiment multi-domain vertical alignment-type liquid crystal display panel 200.
It is described that multi-domain vertical alignment-type liquid crystal display panel of the present invention is not limited to above-mentioned embodiment, as: in first embodiment, the groove 281,282,283,284 of this second substrate 220 also can be replaced by identical shaped a plurality of projections; This first groove 281 can be unequal with width L1, the L2 of the 3rd groove 283, and the pixel electrode width W 1 that the pixel electrode width W 1 that only needs to guarantee this first pixel cell 250 and the ratio W1/L1 of groove 281 width L1 are not equal to this second pixel cell 260 gets final product with the ratio W2/L2 of groove 283 width L2; Two the 3rd sub-projection 243a of two first sub-projection 241a of first projection 241 of this first pixel cell 250 and the 3rd projection 243 of this second pixel cell 260 also can be not parallel, but have certain angle; Two first sub-projection 241a of these two first projections 241 can be connected and constitute a v-shaped structure, and these two the 3rd projections 243 and this data line 223 two second parallel extension 243b also can be connected and roughly constitute a v-shaped structure.
