Abstract
A liquid crystal projector projects an image based on video data inputted from the external. The liquid crystal projector is provided with: a timing control device for outputting a predetermined timing signal synchronous with a horizontal scanning period of the video data; a projection light source for emitting a projection light; a color separation device, coupled to the timing control device, for separating the projection light into R, G and B components to output them in a time divisional manner on the basis of the timing signal; a liquid crystal light valve panel, coupled to the timing control device, for displaying images respectively corresponding to the R, G and B components in a time divisional manner on the basis of the video data and the timing signal, and for converting an output light incident from the color separation device to rays of a projection light corresponding to the displayed images; and a projection lens for magnifying and projecting an output light from the liquid crystal light valve panel.
