Liquid crystal panel
View Patent ↗The present invention relates to a liquid crystal display panel, including an array substrate and a color filter substrate bonded together. The color filter substrate is provided with primary photo spacers, and the top end of the primary photo spacers are provided at the sub-pixel of the array substrate, and one or more sub-pixels corresponds to one primary photo spacer, the primary photo spacers are grouped into at least two sets, the primary photo spacers in each set have a same prescribed location and a same top end shape. The primary photo spacers in the different set have different prescribed locations or different top end shapes. In the liquid crystal display panel of the invention, since the different primary photo spacers are provided at the different locations, therefore, if the alignment deviation occurs when the array substrate and the color filter substrate are bonded together, the alignment deviations of the primary photo spacers at the different prescribed locations will be compensated for each other, so as to ensure the uniformity of the cell thickness.
