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.

Abstract: A display module including a display panel, a supporting member, a first circuit board, and a light blocking member. The display panel includes a display area and a non-display area. The non-display area is bent. The supporting member includes a first surface overlapping the display area; a second surface opposite to the first surface; and a third surface configured to connect the first surface to the second surface. The first circuit board faces the second surface and is electrically connected to the non-display area. The light blocking member contacts a bent area of the non-display area.
