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 flexible substrate and corresponding method of manufacturing are described. The flexible substrate includes a substrate, a first buffer layer, a second buffer layer and a third buffer layer. The first buffer layer, positioned on the substrate, has a plurality of first buffer segments. The second buffer layer, positioned on the first buffer layer, has a plurality of second buffer segments. The third buffer layer, positioned on the second buffer layer, is connected to the first buffer layer via a contact hole between two adjacent second buffer segments. Because the first buffer layer is patterned to include buffer segments, cracking in the first buffer layer is reduced. Because the third buffer layer is connected to segments of the first buffer layer via a contact hole between two adjacent second buffer segments, moisture permeation paths from the substrate into the second buffer layer are blocked, suppressing moisture permeation.

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.
