Abstract

A display panel includes a substrate, at least two repeating units, and a light-shielding layer. Each repeating unit includes a plurality of sub-pixels including a first color sub-pixel and a second color sub-pixel. As a viewing angle increases, a luminance decay rate of the first color sub-pixel is greater than a luminance decay rate of the second color sub-pixel. The light-shielding layer includes a plurality of opening portions including first opening portions respectively corresponding to first color sub-pixels and second opening portions respectively corresponding to second color sub-pixels. Along a first direction, a difference between a length of a first opening portion and a length of a portion of the first color sub-pixel exposed from the first opening portion is greater than a difference between a length of a second opening portion and a length of a portion of the second color sub-pixel exposed from the second opening portion.
