Abstract

A display device is described that includes an optical member such as a camera. According to an exemplary embodiment, the display device includes: a substrate that overlaps a light transmission area, a display area that surrounds the light transmission area, and a boundary area that is disposed between the light transmission area and the display area; a first light blocking member that is disposed on the substrate and overlaps the boundary area; a window that overlaps the substrate; and a second light blocking member that is disposed between the first light blocking member and the window, and overlaps the boundary area, wherein the first light blocking member includes a first opening that overlaps the light transmission area, the second light blocking member includes a second opening that overlaps the light transmission area, and a diameter of the first opening is larger than a diameter of the second opening.
