Abstract: A display device may include a substrate, a display element, and an organic insulating layer. The substrate may include a first area, a second area, and a bent area. The bent area may be connected between the first area and the second area, may be bent according to a bending axis, and may be narrower than the first area in a direction parallel to the bending axis. The display element may overlap the substrate. The organic insulating layer may be spaced from the display element, may be arranged at an edge of the substrate, and may only partially overlap a first face of the substrate. A face of the organic insulating layer may be coplanar with a second face of the substrate.

Abstract: A display apparatus includes a first pixel circuit and a second pixel circuit. The first pixel circuit includes a first driving transistor and a first storage capacitor having a first lower storage electrode connected to a gate of the first driving transistor and a first upper storage electrode overlapping the first lower storage electrode. The second pixel circuit includes a second driving transistor and a second storage capacitor including a second lower storage electrode connected to a gate of the second driving transistor and a second upper storage electrode overlapping the second lower storage electrode. A second overlapping area of the second lower storage electrode and the second upper storage electrode is about twice to about four times a first overlapping area of the first lower storage electrode and the first upper storage electrode.
