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.
