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 the 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.
