Abstract: Disclosed is a display device that includes a substrate including a first display region and a second display region adjacent to the first display region, a pixel layer disposed on the substrate and including transmission regions that overlap the first display region, and a protective layer below the substrate. The protective layer includes a first part below the first display region and a second part below the second display region. The first part has a thickness less than a thickness of the second part.
