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.
