DISPLAY PANEL AND MANUFACTURE METHOD THEREOF

摘要

The present invention provides a display substrate and a manufacture method thereof. The display substrate locates the common electrode (10) above the pixel electrode (20) and overlapping with the pixel electrode (20) on the same substrate (100); the common electrode (10) comprises a first opening (OP1), a second opening (OP2), a third opening (OP3) and a fourth opening (OP4) which are symmetrically located to one another; the first opening (OP1) comprises an eleventh extension part (OP11) extending along a tilt direction, a twelfth extension part (OP12) perpendicular with the eleventh extension part (OP11) and a thirteenth extension part (OP13) perpendicular with the eleventh extension part (OP11), of which the liquid crystal molecules can be aligned along different directions to form multi-domains in a plurality of pixel areas, and thus, the color washout can be improved, and meanwhile, the brightness descend caused by the crystal textures formed at edges of respective domains can be diminished or prevented.

主权项
