Abstract

A light emitting display device includes a display panel including a light emitting area and a non-light emitting area; a phase delay layer disposed on the display panel; and a polarizer and an additional polarizer disposed on the phase delay layer. The display panel includes a transistor disposed on a substrate, an organic film overlapping the transistor and including an opening, a first electrode, an emission layer disposed on the first electrode and disposed corresponding to the light emitting area, and a second electrode disposed, the first electrode, the emission layer, and the second electrode form a light emitting diode (LED), the additional polarizer includes a polarization portion overlapping the opening of the organic film in a plan view and a non-polarization portion disposed in a region where the polarization portion is not disposed, and the polarization portion is disposed in a portion of the non-light emitting area.
