Viewing angle control film and display device comprising the same

A viewing angle control film comprising:

• 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,
• wherein the light conversion layer comprises:
• 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,
• wherein the control unit is configured to apply a pulse voltage that swings between a positive signed first voltage and a negative signed second voltage having a same duration as that of the first voltage, and adjust a magnitude of the first voltage in each drive mode, and
• wherein a private mode having a narrow viewing angle and a share mode having a wide viewing angle are included, and the control unit applies the pulse voltage in the share mode.
