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 top-emission type light emitting display device and a corresponding manufacturing method are described. A device substrate has display area and non-display areas. In the display area are formed: a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode; and an organic light emitting element including an anode, an organic light emitting layer, and a cathode. In the non-display area a second voltage supply wire is formed on, and overlaps with, a first voltage supply wire. An anti-burning layer is disposed between the first voltage and the second voltage supply wires. The anti-burning layer is an insulation layer with the same thickness as a space sufficient to suppress burning of the wires in the overlapping region between the first voltage supply wire and the second voltage supply wire, thus improving reliability and manufacturing yield of the device.

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.
