A display device includes: a substrate including a display area and a peripheral area adjacent to the display area, pixels disposed in the display area on the substrate, each of the pixels including a pixel transistor and an emission element connected to the pixel transistor, and a driver disposed in the peripheral area on the substrate and including a driver transistor. The driver transistor includes an active pattern, a first gate pattern disposed on the active pattern and overlapping a first channel region of the active pattern, a second gate pattern disposed in a same layer as the first gate pattern and overlapping a second channel region of the active pattern, a first electrode pattern disposed on the active pattern and connected to a source region of the active pattern, and a second electrode pattern disposed on the active pattern and connected to a drain region of the active pattern.

Display device

A display apparatus includes a substrate including a display region and a non-display region, a display element layer, a pad group, a touch electrode layer, and a touch insulating layer. The display element layer includes display elements provided in the display region in a plan view. The pad group may include output pads provided on substrate and provided in the non-display region in the plan view. The touch electrode layer is provided on the display element layer. The touch insulating layer is provided on the display element layer and contacts the touch electrode layer. An intaglio pattern is provided in the touch insulating layer overlapped with the non-display region, and the intaglio pattern is not overlapped with the pad group.

Display apparatus

An organic light emitting diode display device includes a substrate, first and second active patterns, and first and second sub-pixel structures. The substrate has a first sub-pixel circuit region including a first driving transistor region and a second sub-pixel circuit region including a second driving transistor region. The first active pattern is disposed in the first sub-pixel circuit region and has a first bent portion in the first driving transistor region. The second active pattern is disposed in the second sub-pixel circuit region and has a second bent portion in the second driving transistor region. In a direction in a plan surface, the first active pattern has a first recess formed by the first bent portion, and the second active pattern has a second recess formed by the second bent portion. An area of the second recess is less than that of the first recess.
