Abstract: A display device includes a first substrate including a display area in which a plurality of pixels are arranged and a light transmitting area disposed in the display area, an interlayer insulating layer covering the display area and exposing the light transmitting area, an inner sidewall of the interlayer insulating layer defining the light transmitting area, and an inorganic film disposed directly on the first substrate in the light transmitting area and overlapping the entire light transmitting area. A size of the light transmitting area is larger than a size of a pixel of the plurality of pixels.
