Abstract

The application relates to a display panel and a display device, wherein a first light-emitting unit and a second light-emitting unit share a second electrode, the first sub-electrode and the second sub-electrode are connected with an array substrate, and the first light-emitting unit and the second light-emitting unit are connected with the same array substrate. In addition, since the front projection of the first light emitting unit and the second light emitting unit in the first direction is overlapped, the integration level of the display panel is also improved. In addition, the same array substrate can respectively control the first light-emitting unit and the second light-emitting unit, and the first light-emitting unit and the second light-emitting unit can be respectively displayed as separate pictures during double-sided display, so that the mirror image problem can not occur, and the display picture of double-sided display is optimized.
