Abstract: A partial transparent display device has a light transmitting function and a light emitting function in one area. The partial transparent display device includes a substrate, a transparent emission area, a driving emission area, and a pad part. The transparent emission area is disposed to be adjacent to one side of the substrate. The driving emission area is disposed to be adjacent to the transparent emission area and to be closer to the other side opposite to the one side. The pad part extends from the driving emission area and is disposed on the other side. The driving emission area includes driving emission pixels which are defined by scan lines, data lines, and pixel driving power supply lines. The transparent emission area includes transparent emission pixels which are defined without the scan lines, the data lines, and the pixel driving power supply lines.
