Abstract: A display device includes a display portion having a substantially rectangular area with rounded edges in which a plurality of data lines are arranged. The display device includes a first area corresponding to a rounded edge part and a second area corresponding to a straight edge part adjacent to the first area. A data driving circuit includes a plurality of output channels configured to output data voltages. Odd-numbered output channels output data voltages according to a sequential arrangement of data lines in the second area. Even-numbered output channels output data voltages according to a reverse sequential arrangement of data lines in the first area.

Abstract: A display device includes a substrate including a display region, a first non-display region in the display region and a second non-display region outside the display region. A pixel array layer is disposed on the display region of the substrate. An encapsulation layer is disposed on the display region. The encapsulation layer is disposed on the first and second non-display regions of the substrate. The first non-display region includes a through hole penetrating the pixel array layer and the substrate. An encapsulation groove is spaced apart from the through hole. An inner wall of the through hole and an inner wall of the encapsulation groove are at least partially covered with the encapsulation layer. An end face of the encapsulation layer facing away from the pixel array layer has an irregular shape when viewed from a side of the substrate opposite the pixel array layer.
