Abstract

A display device includes a substrate. The substrate includes a display area and a non-display area, and the display area includes an emission area and a non-emission area. A display element layer includes a light emitting element on the emission area of the substrate. A bank is on the display element layer and overlaps the non-display area and the non-emission area of the substrate in a plan view. A color conversion layer is on the display element layer, overlaps the emission area in the plan view, and is to convert a color of light emitted from the light emitting element. An organic insulating layer is on the color conversion layer and the bank. A maximum thickness of the bank is about 4 μm to about 20 μm. An average inclination angle of a first side surface of the bank adjacent to an edge of the substrate in the non-display area based on an upper surface of the substrate is less than or equal to about 45 degrees.
