Abstract

A display apparatus includes a substrate including a foldable area including a first foldable area adjacent to a first non-folded area and a second foldable area adjacent to a second non-folded area, a pixel-defining layer disposed over the substrate, and a light-blocking layer disposed over the pixel-defining layer. The pixel-defining layer defines a (1-1)st lower opening, a (1-2)nd lower opening, a (1-3)rd lower opening, and a (1-4)th lower opening. The light-blocking layer defines a (1-1)st upper opening, a (1-2)nd upper opening, a (1-3)rd upper opening, and a (1-4)th upper opening. The (1-3)rd upper opening is shifted to one side facing the first non-folded area of the (1-3)rd lower opening. The (1-4)th upper opening is shifted to one side facing the second non-folded area of the (1-4)th lower opening.
