## Abstract

A display panel includes a plurality of sub-pixel structures and a plurality of transfer elements. The sub-pixel structures include a plurality of first sub-pixel structures. A data line of each of the first sub-pixel structures is disposed adjacent to a corresponding transfer element, and a scan line of each of the first sub-pixel structures is electrically connected to the corresponding transfer element. The first sub-pixel structures include a plurality of first-type sub-pixel structures and a plurality of second-type sub-pixel structures. When the display panel displays a grayscale picture, each of the first-type sub-pixel structures has first brightness, each of the second-type sub-pixel structures has second brightness. The first brightness is less than the second brightness. A total number of the first sub-pixel structures of the display panel is A, a number of the first-type sub-pixel structures in the first sub-pixel structures is a, and 50%<(a/A)<100%.
