Abstract
A display panel and a display device are provided, and the display panel includes a circuit layer and a pixel layer disposed over the circuit layer. The pixel layer includes a first region used to form a first sub-pixel and a second region used to form a second sub-pixel. The ability of light to pass through the liquid crystal molecules over the first and second subpixels sequentially decreases. The circuit layer includes a driving circuit disposed opposite to the first region, and a difference between image brightness above the first region and image brightness of above the second region is within a predetermined range.
