1. A display device comprising:
a substrate;
a display element on the substrate, the display element comprising a pixel electrode and an opposite electrode opposite to the pixel electrode;
a pixel defining layer covering an edge of the pixel electrode and having an opening exposing a central portion of the pixel electrode;
a spacer above the pixel defining layer;
a thin-film encapsulation layer on the display element, the thin-film encapsulation layer comprising at least one inorganic layer and at least one organic layer; and
a pattern layer between the thin-film encapsulation layer and the spacer, the pattern layer comprising a bottom surface contacting an upper surface of the spacer, a first surface opposite to the bottom surface, and an inclined second surface connecting the bottom surface and the first surface,
wherein the opposite electrode continuously covers the first surface of the pattern layer and the inclined second surface of the pattern layer, and
wherein the at least one inorganic layer has a first thickness on the first surface of the pattern layer and a second thickness on the inclined second surface of the pattern layer,
the first thickness is greater than or equal to the second thickness, and a ratio of the second thickness to the first thickness is about 0.51 or more,
wherein a width of the inclined second surface of the pattern layer increases from the bottom surface to the first surface of the pattern layer, and
wherein a width of the bottom surface of the pattern layer is smaller than a width of the upper surface of the spacer.
