| Abstract | The present invention provides a liquid crystal display panel. By providing one convex part respectively on the array substrate corresponding to two sides of each sub spacer, which is equivalent to forming one recess between two convex parts, and thus to make the sub spacer being wedged in the recess. Then, the horizontal offset hardly occurs to the array substrate and the color filter substrate. The issue of V-Crosstalk of the traditional liquid crystal display panel due to pixel light leak can be solved to promote the display quality of the display panel. |
