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.

Abstract: A method of fabricating a display panel including a display region having a first pixel region where pixels are disposed, and a sensing region having a second pixel region where pixel groups are disposed and a light transmitting part disposed between the pixel groups, is discussed. The method can include forming a light shield layer at least in the sensing region, wherein the light shield layer includes an opening hole corresponding to the light transmitting part and exposes the light transmitting part to a laser beam through the opening hole. The method can further include forming a metal layer spaced apart from the light blocking layer in the first pixel region of the display region and the sensing region, and irradiating the laser beam to at least the sensing region to remove the metal layer from the light transmitting part.

Abstract: Disclosed is a display device which includes: a plurality of gate lines arranged in a first direction; a plurality of data lines arranged in a second direction crossing the first direction; a plurality of jumping electrodes each disposed a first edge portion of each of the data lines; and a plurality of shield portions disposed between the jumping electrodes. Such a display device allows the shield portions to be disposed between the jumping electrodes. As such, the display device can prevent a light leak phenomenon due to an electric field which is generated by the shortened distance between the front edge portions of the data lines.
