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.
