摘要： A display panel and a display device is provided in the present disclosure, which belongs to the field of display technologies. The display panel includes a base substrate and a plurality of pixel circuits disposed on the base substrate. At least two pixel circuits in a same column are coupled with a same first initial power line, such that only a small quantity of signal lines need to be disposed on the base substrate. Accordingly, an area which needs to be occupied by the signal lines and is of the base substrate becomes smaller, thereby facilitating high-resolution design of the display panel.
