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.
