A display device includes a display panel having a plurality of pixels. The device includes a data driver configured to supply a data voltage to the plurality of pixels via a plurality of data lines using a sensing result of the plurality of pixels via a first reference voltage line, a second reference voltage line, and a third reference line. The device includes a gate driver configured to supply a gate signal to the plurality of pixels via a plurality of gate lines. Each of the plurality of data lines is branched into a plurality of sub data lines and each of the plurality of sub data lines is connected to a plurality of sub pixels having the same color. The reference voltage lines are connected to the plurality of sub pixels. The device improves a sensing speed of the sub pixel.

Display device

An organic light-emitting diode (OLED) display device capable of improving light extraction efficiency and lifetime is disclosed. In the OLED display device, a protective layer having a convex shaped protruding pattern is arranged in a light emitting area at a central portion of a substrate, so that only the light emitting area has a selectively convex protruding shape. Accordingly, in the OLED display device, in a process of forming an organic light emitting layer, the protruding pattern can artificially offset the organic light emitting layer arranged at the central portion of the substrate being sagged, by a protective layer having a convex shaped protruding pattern. As a result, the OLED display device can improve a problem of thickness non-uniformity of the central portion and an edge portion of the substrate due to a sagging phenomenon of the organic light emitting layer.
