Abstract: A display apparatus may include a first transistor, a second transistor, and a capacitor. The first transistor includes a first semiconductor layer and a first gate electrode insulated from the first semiconductor layer. The first semiconductor layer includes a first silicon semiconductor. The second transistor includes a second semiconductor layer and a second gate electrode insulated from the second semiconductor layer. The second semiconductor layer includes a first oxide semiconductor. The capacitor includes a first electrode and a second electrode. The second electrode overlaps the first electrode and extends from the second semiconductor layer.

Abstract: The present disclosure provides a display panel. In order to reduce a parasitic capacitance that may occur between a data line and a semiconductor layer and a crosstalk caused by the parasitic capacitance, a display panel includes a substrate, a driving thin film transistor on the substrate, including a driving semiconductor layer and a driving gate electrode, a compensation thin film transistor on the substrate, including a compensation semiconductor layer and a compensation gate electrode, a node connection line electrically connecting the driving thin film transistor to the compensation thin film transistor, a scan line extending in a first direction on the substrate, and a gate connection line electrically connected to the scan line, which includes the compensation gate electrode, wherein the compensation semiconductor layer is closer to the driving semiconductor layer than the scan line when viewed on a plane.

Abstract: A display device includes a pixel circuit including a first pixel and a second pixel. The first pixel arranged in a first row and the second pixel arranged in a second row are commonly connected to one scan line, the number of the scan lines required by the display device may be reduced to half. An active period of the first selection signal does not overlap an active period of the second selection signal. A scan on time of the scan signal overlaps one of the active period of the first selection signal and the active period of the second selection signal.

Abstract: An organic light-emitting diode (OLED) display and a method of manufacturing the same are disclosed. In one aspect, the display includes a plurality of pixel electrodes positioned over a substrate and separate from each other, a plurality of auxiliary wirings between the pixel electrodes, a pixel-defining layer over the pixel electrodes except for a central portion of the pixel electrodes and at least a portion of each of the auxiliary wirings, an intermediate layer over the pixel-defining layer and having a plurality of openings formed over the portion of each of the auxiliary wirings, and an opposite electrode positioned over the intermediate layer and facing the pixel electrodes, the opposite electrode electrically contacting the auxiliary wirings via the openings. The auxiliary wirings extend in a first direction and separate from each other by a first distance. The openings are aligned in a diagonal direction crossing the first direction.
