Pixel and viewing angle control display device including the same

A viewing angle control display device comprising:

• a substrate;
• a plurality of pixels on the substrate;
• a lens assembly on the plurality of pixels, the lens assembly comprising a plurality of pixel lenses;
• a reflective layer including a plurality of apertures formed in the reflective layer,
• wherein a pixel of the plurality of pixels comprises:
• a thin film transistor (TFT) array layer on a substrate, the TFT array layer comprising circuit elements;
• and
• a light emitting element layer on the TFT array layer, the light emitting element layer comprising a first electrode layer, a second electrode layer, and a light emitting layer between the first electrode layer and the second electrode layer,
• wherein the reflective layer is disposed on the light emitting element layer,
• wherein the pixel overlaps one aperture of the plurality of apertures without overlapping any other aperture of the plurality of apertures in a plan view of the pixel, and
• wherein the light emitting layer generates light that is guided by the reflective layer such that the light is emitted through an aperture of the plurality of apertures, and
• wherein the viewing angle control display device further comprises:
• a thin film encapsulation layer between the light emitting element layer and the reflective layer, the thin film encapsulation layer comprising an inorganic thin film or an organic thin film;
• and
• a passivation layer between the lens assembly and the reflective layer.
