Abstract
Disclosed are a display panel and a display device. The display panel includes a substrate and multiple organic light-emitting units located in the display region on a first side of the substrate, where an area of at least one of organic light-emitting units in the second display region is smaller than an area of each of organic light-emitting units with a same light-emitting color in the first display region, and/or, density of the organic light-emitting units in the first display region is greater than density of the organic light-emitting units in the second display region. The second display region includes at least one quantum dot light-emitting unit, which does not overlap the organic light-emitting units; and each of the at least one quantum dot light-emitting unit emits light of a same color as at least one of the organic light-emitting units located in the second display region.
