Abstract
A viewing angle controllable liquid crystal display device, as embodied, includes: a liquid crystal panel including a plurality of color pixels, each of the color pixels having color subpixels and at least one interference subpixel; an input unit for inputting color subpixel data to be supplied to the color subpixels and inputting area data of an image whose security is requested; an interference data generating unit for generating interference subpixel data to be supplied to the interference subpixels; an interference area control unit for controlling the interference data generating unit to output the interference subpixel data corresponding to the area data; a data combining unit for combining the interference subpixel data with the color subpixel data; and a driving circuit for driving the color subpixels and the interference subpixels on the liquid crystal panel using the combined data from the data combining unit.
