Abstract
The present invention provides a display panel. The display panel includes at least three sub-pixel regions. The sub-pixel regions are arranged along a direction of a scan line. A channel region of each driving TFT in the same sub-pixel region has a same width-to-length ratio. Along a direction from a signal input end to a signal output end of the scan line, the width-to-length ratio of the channel region of each driving TFT of any of the sub-pixel regions is smaller than that of a previous one of the sub-pixel regions.
