摘要： A light emitting display device according to an embodiment includes a driving element layer disposed on a substrate, a light emitting element layer disposed on the driving element layer, and an external light decreasing layer disposed on the light emitting element layer. The light emitting element layer includes an anode, a pixel defining film having a first opening exposing at least a portion of the anode, a light emitting layer disposed on the anode in the first opening of the pixel defining film, and a cathode disposed on the light emitting layer and the pixel defining film. The external light decreasing layer includes an inorganic material having an absorption coefficient of greater than or equal to about 1.5, and includes a reflection control layer having a second opening corresponding to the first opening of the pixel defining film.
