Abstract: An organic light emitting diode display is provided, which selectively disconnects one section of a scan line to darken a defective pixel when a defect occurs in a pixel provided with Thin Film Transistors (TFTs). The organic light emitting diode display includes four subpixel regions arranged in a 2×2 matrix on a substrate, a first horizontal scan line, a second horizontal scan line, a first vertical scan line, and a second vertical scan line. The first horizontal scan line passes through first and third subpixel regions. The second horizontal scan line passes through second and fourth subpixel regions. The first vertical scan line and the second vertical scan line connect the first horizontal scan line and the second horizontal scan line.

Abstract: Provided are a display device and a method of manufacturing the same. A display device includes a coplanar thin-film transistor and a capacitor. The coplanar thin-film transistor comprises a gate electrode, an active layer including an oxide semiconductor, a source electrode and a drain electrode. The capacitor comprises a lower electrode, intermediate electrode and upper electrode. And the lower electrode is comprised of the same material as the active layer, and is conductivized. Also, the upper electrode is connected to the lower electrode. By using the conductivized lower electrode, the capacitor is configured to operate as multiple capacitors. Thus, the size of the capacitor is reduced, and sufficient capacitance may be secured with the capacitor with a smaller area. In this way, the area of each sub-pixel in the display device may be reduced, thereby achieving high resolution.
