PURPOSE: A view angle control sheet formed on a display device is provided to enable a user to clearly watch the display device in case that the display device is arranged in parallel or at under 20 degrees. CONSTITUTION: A sheet base(300) is formed on a display device(210). A prism unit(302) controls a path of light outputted from the display device. The prism unit includes first prism patterns(310) and second prism patterns(312). The first prism patterns have a refraction rate different from the sheet base, and control the angle of the light incident through the sheet base. The second prism patterns protect the first prism patterns. A protection unit(304) is formed on the prism unit, and protects the prism unit. The protection unit has a scratch resistance function, an antistatic function, an anti-fingerprint function and an anti-reflection function. |
