Abstract
A pixel structure, including pixels arranged in a matrix. Each pixel includes sub-pixels arranged along a row direction, including first type sub-pixels and at least one second type sub-pixel. The sub-pixels in different rows are arranged alternately such that each sub-pixel column includes the same numbers of the second type sub-pixels. Each sub-pixel has a color resist and a photo spacer disposed thereon. The color resists of the second type sub-pixels have a sectional difference from the color resists of the first type sub-pixels, and the sectional difference is greater than a height of the photo spacer of each of the first type sub-pixels. For each second type sub-pixel, a photo spacer (PS) stage is extended from a corresponding common voltage line, and the color resist is disposed on the corresponding PS stage to form the sectional difference. Thus, each common voltage line has the same number of PS stages.
