Viewing angle control film and display device comprising the same

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,
• wherein an operation of the viewing angle control film includes a private mode operating in a narrow viewing angle, the share mode operating in the wide viewing angle, and a switch mode between the private mode and the share mode, and
• wherein the controller applies a voltage greater than the pulse voltage in the switch mode.
