A display device including a control circuit layer and a self-illumination layer is provided. The control circuit layer has a plurality of control circuit blocks distributed along a cross direction. The self-illumination layer is disposed on the control circuit layer and has a plurality of self-illumination blocks distributed along the cross direction. The self-illumination blocks respectively connect to corresponding control circuit blocks. In the cross direction, the self-illumination block extends an offset distance out of the corresponding control circuit block toward a first side. A self-illumination block closer to the first side has a larger offset distance.
