Display apparatus including light receiving pixel area

An electroluminescent display device is disclosed. The disclosed electroluminescent display device includes a substrate including a plurality of pixel regions; a plurality of light emitting diodes spaced apart from each other on the substrate and each corresponding to the plurality of pixel regions, respectively; a plurality of encapsulation films respectively covering each of the light emitting diodes of the plurality of light emitting diodes, wherein the plurality of encapsulation films has a first refractive index; a first partition wall disposed between each of the encapsulation films of the plurality of encapsulation films, wherein the first partition wall corresponds to a boundary between the plurality of pixel regions and has a second refractive index lower than the first refractive index; and a color filter layer disposed on the plurality of encapsulation films and the first partition wall.

Disclosed herein is a holographic display which enables stereoscopic display of colors by changing a structure and mitigates a flickering effect by lowering the response speed. The holographic display may deliver an image to different positions for the left eye and right eye at the same time, thereby lowering the frequency necessary for supply of holographic image information. Thereby, the holographic display may address the issues of the afterimage effect and flickering effect in a liquid crystal panel-based spatial light modulator.
