Abstract: A display device having a switchable viewing angle includes a first polarizer which transmits light of a P-wave or S-wave, a viewing angle control panel which is disposed above the first polarizer, includes a lower electrode and an upper electrode, and a liquid crystal layer disposed between the lower electrode and the upper electrode to selectively change the light of P-wave or S-wave to an S-wave or P-wave, and a second polarizer which is disposed above the viewing angle control panel and has a transmission axis perpendicular to a transmission axis of the first polarizer. Therefore, the mode may be switchable to the privacy mode and the share mode and in the share mode, the luminance may be improved without increasing the power consumption.

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.
