Abstract

A pixel structure and a display panel having the pixel structure are disclosed by the present application. The pixel structure includes a plurality of pixel units arranged in an array. The pixel units are arranged respectively along a first direction and a second direction perpendicular to the first direction. Each of the plurality of pixel units comprises a first sub-pixel, a second sub-pixel, and a third sub-pixel which have different colors. In the second direction, a distance between the third sub-pixels is different from a distance between the first sub-pixels and is different from a distance between the second sub-pixels. According to the pixel structure of the present application, the pixel units can be arranged more compact, therefore the pixel pitch is reduced and the PPI is improved.
