Abstract: Provided is a viewing angle varying film. The viewing angle varying film includes a first film, a second film that overlaps the first film and is spaced apart from the first film, a first electrode on the first film, a second electrode on the second film, and a viewing angle varying layer between the first electrode and the second electrode. The viewing angle varying layer includes a plurality of first structures and a plurality of second structures including colored particles and are spaced apart from each other. At least one or more of a height, a width, and a shape of the plurality of first structures and the plurality of second structures is different. Accordingly, various viewing field characteristics may be satisfied.

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.
