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.

Abstract: A display device includes a substrate including an emission area and a non-emission area. A light emitting layer is disposed on a pixel electrode and within a first opening. A common electrode is disposed on the light emitting layer, in contact with a first bank layer within a second opening. An encapsulation layer is disposed on the common electrode and a second bank layer. A protruding tip of the second bank layer includes a side surface of the second bank layer. The encapsulation layer includes an inorganic layer covering the common electrode. The protruding tip and a fluidized layer are disposed on the inorganic layer. The fluidized layer includes a first portion 10 disposed on the common electrode and a second portion disposed on the second bank layer. The first portion and the second portion are spaced apart from each other.
