Abstract: Provided is a display panel including a display area, which includes an optical component arrangement region including a light-blocking region and light-transmitting region units distributed in rows and columns. Each light-transmitting region unit includes first and second sets of light-transmitting regions that are arranged along a first direction. The first set of light-transmitting regions includes a first light-transmitting region and a second light-transmitting region arranged along a second direction, and the second set of light-transmitting region includes a third light-transmitting region and a fourth light-transmitting region arranged along the second direction. The first direction intersects with the second direction. Each light-transmitting region has a length direction. An angle formed between the length direction and the first direction is within a range of 10° to 40°. In each light-transmitting region unit, the length direction of each light-transmitting region points to an area surrounded by the first to fourth light-transmitting regions.

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.
