The present invention provides a liquid crystal display device, having light-converging member provided for each pixel or each pixel row consisting of a plurality of pixels for converging the light incident from the outside, first light path converting member for converting the converged light into a parallel light, light separating member for separating the parallel light into its red-, green- and blue-light components, a liquid crystal cell for controlling the transmitting amount of each light component, and control member for controlling the light transmittance of the liquid crystal cell for a plurality of pixels by applying a voltage to the liquid crystal cell.
