Abstract: Disclosed is a display device for increasing an aperture ratio of a transmissive part. The display device includes data lines overlapping with one or more of the pixels emitting light to display an image. Each pixel includes subpixels arranged within the pixel along a same direction as the data lines. The display device further includes transmissive parts arranged in the first direction and corresponding to adjacent pixels. In addition to the data lines overlapping the pixels, the display device may include power lines and reference voltage lines parallel with the data lines and overlapping with the pixels. The display device may include scan lines and sensing lines arranged to cross the transmissive parts and data lines. As a result, the number of lines crossing the transmissive parts is reduced, thereby increasing an aperture ratio of the transmissive parts.

Abstract: A gate driver and a display device including the gate driver are discussed. The gate driver in one example includes a shift register configured to control charging and discharging of a Q node and a QB node, and i output buffers sequentially connected to the shift register, where i is a natural number of at least 2. Each output buffer is configured to output a gate signal to a corresponding gate line in response to a voltage of the Q node and a voltage of the QB node. The gate driver further includes a dummy output buffer connected to the last stage of the shift register and configured to output a dummy signal to a dummy line in response to the voltage of the Q node.
