Abstract: A display panel and a display device are provided in the present disclosure. The display panel includes a plurality of pixels, including first pixels and second pixels, where each of the first pixels includes a first light-emitting element connected with a first pixel circuit; the first pixel circuit includes a first drive transistor; each of the second pixels includes a second light-emitting element connected with a second pixel circuit; and the second pixel circuit includes a second drive transistor. The display panel further includes a display region, including an optical component region and a first display region, where the first light-emitting element is in the optical component region; the second light-emitting element is in the first display region.

Abstract: A display panel and a display device are provided in the present disclosure. The display panel includes first pixels and second pixels, and further includes a display region including an optical component region and a regular display region. First light-emitting elements are in the optical component region; second light-emitting elements are in the regular display region; and a density of the light-emitting elements in the optical component region is less than a density of the light-emitting elements in the regular display region. The first pixels include first blue pixels, first red pixels, and first green pixels; a width-to-length ratio of a first drive transistor corresponding to a first blue pixel is R1, a width-to-length ratio of a first drive transistor corresponding to a first red pixel is R2, and a width-to-length ratio of a first drive transistor corresponding to a first green pixel is R3, where R1>R2>0 and/or R1>R3>0.

Abstract: A display panel and a display device are provided. The display panel includes a display area, including a first display area and repeating units that including a first light-emitting element column, a second light-emitting element column, a third light-emitting element column and a fourth light-emitting element column. The second light-emitting element column and the fourth light-emitting element column each includes a third color light-emitting element, and third color light-emitting elements in the second light-emitting column and the fourth light-emitting element column are arranged in a staggered manner in the first direction. In a direction perpendicular to a plane of the display panel, a light-emitting element includes an anode, a light-emitting material layer and a cathode stacked in sequence; and in the first display area, in the direction perpendicular to the plane, in the third color light-emitting element, a shape of the anode includes an arc-shaped edge.
