    摘要： A display apparatus that prevents visual recognition of flickering in each of display areas having different resolutions includes a first pixel circuit, a first display element, a second pixel circuit, and a second display element. The first pixel circuit includes: a first driving transistor configured to control a first current that flows to the first display element; and a first initializing transistor configured to apply a first initializing voltage to a gate of the first driving transistor in response to a first scan signal. The second pixel circuit includes: a second driving transistor configured to control a second current that flows to the second display element; and a second initializing transistor configured to apply a second initializing voltage having a level different from a level of the first initializing voltage to a gate of the second driving transistor in response to the first scan signal.

    摘要： A display device includes a first active pattern disposed on a substrate and including a first material, a second active pattern including a second material that is different from the first material of the first active pattern, a voltage line disposed under the second active pattern, a horizontal transmission line disposed on the second active pattern, and extending in a first direction and a connection pattern spaced apart from the horizontal transmission line, disposed on a same layer as the horizontal transmission line, and making electrical contact with the second active pattern and the voltage line. The horizontal transmission line and the voltage line may be spaced apart from each other and the second active pattern and the voltage line may make contact with each other through the connection pattern. Accordingly, a contact resistance value may be reduced, and a distribution of contact resistance values may resultantly be reduced.

    摘要： A display device includes a first active pattern disposed on a substrate, a first gate electrode disposed on the first active pattern, a second active pattern disposed on the first gate electrode, being electrically connected to the first gate electrode, and including an extension part extending in a first direction and a protrusion part protruding from the extension part in a second direction crossing the first direction, and a voltage line disposed on the second active pattern, extending in the first direction, and overlapping the protrusion part in an overlapping region. The voltage line contacts the protrusion part through a first contact, and the first contact entirely overlaps the overlapping region on a plane.

    摘要： A TFT substrate includes a first active pattern, a first gate insulation, and a first gate. A second gate is on a second gate insulation covering the first gate. A source connection electrode contacts a source region of the first active pattern. A drain connection electrode contacts its drain region. A second active pattern is on a first insulation covering the second gate. A third gate insulation covers the second active pattern. A third gate is disposed on the third gate insulation. A second insulation interlayer covers the third gate. A first source, a first drain, a second source, and a second drain are disposed on the second insulation interlayer. The first source and the first drain contact the source connection electrode and the drain connection electrode. The second source and the second drain contact a source region and a drain region of the second active pattern.

    摘要： A display panel includes a base layer including a first area and a second area. At least one inorganic layer disposed on the base layer overlaps the first area and the second area. The at least one inorganic layer comprises a lower groove. A first thin-film transistor is disposed on the at least one inorganic layer. The first thin-film transistor includes a silicon semiconductor pattern. A second thin-film transistor is disposed on the at least one inorganic layer. The second thin-film transistor includes an oxide semiconductor pattern. A plurality of insulation layers overlap the first area and the second area. An upper groove extends from the lower groove. A signal line is electrically connected to the second thin-film transistor. An organic layer is disposed in the lower groove and the upper groove. A light emitting element is disposed on the organic layer.
