Abstract

Display panel and display device are provided. The display panel includes a plurality of subpixels. A subpixel of the plurality of subpixels includes a pixel circuit and a light emitting element that are electrically connected. The pixel circuit includes a first transistor. A first electrode of the first transistor is connected to a first reference voltage signal terminal. A second electrode of the first transistor is electrically connected to an anode of the light emitting element. In a light emitting retention stage of the subpixel of the plurality of subpixels, the first reference voltage signal terminal is connected to a negative potential signal or a ground potential signal. The plurality of subpixels includes at least a first subpixel and a second subpixel, and a color of the first subpixel is different from a color of the second subpixel.
