Abstract
An object of the present invention is to provide a color image display apparatus which can easily display a full-color animation of VGA class and attains reduction in size and lowering of price and which facilitates full-color gradation control. In order to achieve the object, a color image display apparatus includes a shutter control circuit that slices color component data subjected to color separation in accordance with a slice level, a light source control circuit that controls a light source corresponding to the color component data, one or plural light sources a converting device that converts light from the light source to surface light source light, a shutter which makes light of a corresponding pixel pass therethrough and cuts off the light and which is made of liquid crystal as a main material, and a timing circuit that generates operation timings for the shutter control circuit and the light source control circuit, in which the shutter control circuit transfers one line of slice data to the shutter sequentially on a slice level basis, the light source control circuit turns on the light source corresponding to the source data, and the shutter makes the light from the light source, which corresponds to the slice data representing gradation of the pixel, pass therethrough and cuts off the light to display an image.
