1. A viewing angle control film comprising:
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,
wherein the light conversion layer includes:
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 plurality of partition walls and arranged at regular intervals along the first electrode; and
light blocking particles provided in each of the plurality of containing portions,
wherein the controller applies a pulse voltage in a share mode that operates in a wide viewing angle,
wherein the pulse voltage is applied between the first electrode and the second electrode of the viewing angle control film, and swings between two voltage levels, and
wherein an electric force is alternately applied and not applied between the first electrode and the second electrode in the plurality of containing portions during the share mode.
