Abstract
The invention belongs to the field of display technology, and particularly to a display panel and a display device. The display panel includes a driving substrate and an OLED provided on the driving substrate, the OLED includes a first electrode and a second electrode, and further includes an electron transporting layer, a light-emitting layer and a hole transporting layer provided between the first electrode and the second electrode, and a plurality of color conversion units are uniformly distributed in the electron transporting layer, the light-emitting layer or the hole transporting layer. Advantageous effects of the invention are as follows: with the configuration that the color conversion units are directly doped into any one of the hole transporting layer, the light-emitting layer, and the electron transporting layer, structure of display panel and corresponding manufacturing procedure are simplified, and color purity of the display panel and carrier mobility are efficiently increased.
