Display device

Disclosed is a display device including a substrate including a plurality of sub-pixels. Each of the plurality of sub-pixels includes: a first electrode; a first emission portion on the first electrode, the first emission portion including a first hole function layer and a first emission layer; a first charge generation layer on the first emission portion; a second emission portion on the first charge generation layer, the second emission portion including a second hole function layer and a second emission layer; a second charge generation layer on the second emission portion; and a third emission portion on the second charge generation layer, the third emission portion including a third hole function layer and a third emission layer. And the thicknesses of the first hole function layers respectively located at the plurality of sub-pixels are different. 公开了一种显示设备，包括基板，该基板包括多个子像素。多个子像素中的每一个包括：第一电极；位于所述第一电极上的第一发射部分，所述第一发射部分包括第一空穴功能层和第一发射层；位于所述第一发射部分上的第一电荷产生层；位于所述第一电荷产生层上的第二发射部分，所述第二发射部分包括第二空穴功能层和第二发射层；位于所述第二发射部
