Abstract: A viewing angle control film and a display device including the viewing angle control film are discussed. The viewing angle control film can include a first electrode, a second electrode spaced apart from and facing the first electrode, a light conversion layer disposed between the first electrode and the second electrode, and a control unit configured to adjust a viewing angle of the light conversion layer by adjusting a voltage applied between the first electrode and the second electrode. The light conversion layer can include a plurality of partition walls disposed to be spaced apart between the first electrode and the second electrode, a plurality of containing portions disposed between partition walls and disposed with predetermined gaps along the first electrode, and dispersion liquid, light blocking particles and liquid crystals disposed in each of the plurality of containing portions.

Abstract: A viewing angle control film and a display device including the same are discussed. The viewing angle control film can include a first film including a first electrode, a second film facing the first film while being away from the first film by a predetermined distance and including a second electrode, a light conversion layer disposed between the first film and the second film, and an adhesive layer bonding the light conversion layer and the first film. The light conversion layer can include containing portions disposed at regular intervals along the first film between the first film and the second film, a louver layer surrounding the containing portions while spacing the containing portions and the second film, and light blocking particles provided in each of the containing portions.
