Abstract
The present application provides a display panel and a display device. A light-emitting device layer includes an n-type charge generation layer and a p-type charge generation layer. The light-emitting device layer has a first operating voltage to operate at a preset current density, and has a second operating voltage after operating at the preset current density and a first preset temperature for a preset time. The absolute value of a difference value between the first operating voltage and the second operating voltage is a1, a1 is less than or equal to 1V. The first preset temperature is greater than or equal to 50° C.
