Abstract

A display panel includes a first substrate, first gate lines, first data lines, second data lines, third data lines, fourth data lines, first sub-pixels, second sub-pixels and first shielding electrodes. The first substrate has a plurality of first sub-pixel regions and second sub-pixel regions. The first gate lines extend along a first direction. The first data lines, the second data lines, the third data lines and the fourth data lines extend along a second direction and are sequentially arranged in the first direction. The first sub-pixel is electrically connected to one of the first data line and the second data line. The second sub-pixel is electrically connected to one of the third data line and the fourth data line. The first shielding electrodes extend along the second direction and are disposed in a common boundary between the first sub-pixel region and the second sub-pixel region adjacent to each other.
