Abstract: A light emitting device includes a substrate. A thin film transistor is disposed on the substrate. A first electrode is connected to the thin film transistor. A second electrode at least partially overlaps the first electrode. A first partition wall is disposed between the first electrode and the second electrode. An insulating layer is disposed between the thin film transistor and the first electrode. The insulating layer includes a first part having a first thickness and a second part having a second thickness that is different than the first thickness. The second part of the insulating layer at least partially overlaps the first partition wall.

Abstract: A display device includes a display panel, first and second insulating layers, and a high refractive insulating layer. The display panel includes emission areas and a non-emission area. The first insulating layer is disposed on the display panel, and first openings are defined in the first insulating layer. Second openings, corresponding to the first openings, are defined in the second insulating layer having a refractive index greater than that of the first insulation layer. The high refractive insulating layer has a refractive index greater than that of the second insulating layer. The high refractive insulating layer is disposed on the first and second insulating layers. The first insulating layer includes a first inclined surface defining the first openings, and the second insulating layer includes a second inclined surface defining the second openings. The first inclined surface and the second inclined surface are spaced apart from each other.
