Abstract: A thin film transistor substrate may include a base substrate, a semiconductor member, a gate electrode, a first insulation layer, and a source/drain electrode. The semiconductor member may overlap the base substrate. The gate electrode may overlap the semiconductor member and may be insulated from the semiconductor member. The first insulation layer may be positioned on the gate electrode and may include a first contact hole. The source/drain electrode may include a first discharge hole, may be electrically connected to the semiconductor member, and may be at least partially positioned inside the first contact hole. The first discharge hole may partially expose the semiconductor member.

Abstract: A unit pixel includes a circuit structure, first and second wiring patterns, an interlayer insulating layer, a planarization layer, and a light emission structure. The first wiring pattern disposed on the circuit structure has a first bump structure. The interlayer insulating layer covers the circuit structure and the first wiring pattern. The second wiring pattern disposed on the interlayer insulating layer overlaps the first wiring pattern and has a second bump structure. The planarization layer covers the interlayer insulating layer and the second wiring pattern and includes a via-hole exposing at least a portion of be second wiring pattern. The light emission structure contacts the second wiring pattern through the via-hole. The first and second wiring patterns and the interlayer insulating layer form a capacitor, the light emission structure includes an OLED, and the capacitor is directly connected to an anode of the OLED.

Abstract: A display device includes a display panel, and a protective member disposed outside the display panel. The circuit layer includes a display area and a non-display area, and a first bending line and a second bending line crossing the first bending line are defined are defined in the non-display area. The non-display area includes: a first non-display area bent from the display area with respect to the first bending line; a second non-display area bent from the display area with respect to the second bending line; and a corner non-display area bent from the second non-display area with respect to the first bending line and bent from the first non-display area with respect to the second bending line. A slit is defined in the protective member, and the slit overlap at least a part of the first bending line and the second bending line.
