Abstract: A display device includes: a substrate having an opening area, a display area at least partially extending around the opening area, and a middle area between the opening area and the display area; a light-emitting element in the display area, the light-emitting element including a pixel electrode, an opposite electrode, and a functional layer between the pixel electrode and the opposite electrode; a first separator in the middle area; a second separator between the first separator and the opening area; a first groove between the first separator and the second separator; and a first protective layer between the substrate and the first groove.

Abstract: An organic light emitting display device may include a substrate including a display area and a non-display area; a thin film transistor on the substrate in the display area; a planarization layer covering the thin film transistor; a first electrode on the planarization layer in the display area and connected to the thin film transistor; a pixel defining layer covering the first electrode and including a first opening that exposes a portion of the first electrode to define an emission area; a first light blocking layer on the pixel defining layer and including a photochromic material, a color of the first light blocking layer being reversibly changed by ultraviolet light; an organic light emitting layer on the first electrode; and a second electrode on the organic light emitting layer.
