摘要： A display apparatus includes a display panel including an opening area through which light passes, a non-display area including an opening peripheral area that is around a periphery of the opening area, and a display area including at least one pixel, the display area being around a periphery of the opening peripheral area, an optical film layer disposed on the display panel, and a cover window disposed on the optical film layer. The display panel includes a base substrate, a light emitting structure disposed on the base substrate, a planarization insulating layer disposed on the substrate in the opening peripheral area, and a light blocking pattern disposed on the planarization insulating layer in the opening peripheral area.
