A viewing angle control film and a display device comprising the same are discussed. The viewing angle control film can include a first electrode, a second electrode facing away from the first electrode, a light conversion layer disposed between the first electrode and the second electrode, and a controller configured to adjust a viewing angle of the light conversion layer by controlling 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 the partition walls and arranged at regular intervals along the first electrode, and light blocking particles provided in each of the plurality of containing portions. The controller applies a pulse voltage in a share mode that operates in a wide viewing angle.
