Abstract: A viewing angle controlling film, a backlight unit using the same, and a display device using the same are disclosed. The viewing angle controlling film comprises a first area where light transmittance is not converted; and a second area where light transmittance is converted, wherein the second area includes a light-transmittance conversion portion configured to react with light of a predetermined wavelength range to convert the light transmittance and not to react with light of a wavelength range other than the predetermined wavelength range.

Abstract: A viewing angle limiting apparatus and a display apparatus are provided. The apparatus comprises a first optical member having a plurality of lower light shielding members, and a second optical member having a plurality of upper light shielding members and facing the first optical member. Each of the plurality of upper light shielding members may be spaced apart from each of the plurality of lower light shielding members in a thickness direction of the first optical member and disposed to be alternate with each of the plurality of lower shielding members. Therefore, since a length of each of the lower light shielding members and the upper light shielding members may be formed to be short, the light shielding members may be manufactured more easily than the case that one light shielding member is provided longitudinally up and down, and a defect rate may be lowered, whereby productivity may be enhanced.
