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.
