ABSTRACT:
A color liquid crystal display device capable of displaying color images comprises an input pen for use in determining the individual position for color display on the screen of a liquid crystal display panel, a coordinate detector for recognizing the position as designated by the input pen to output the position as the corresponding coordinate data, a color designator circuit for designating a color as presently selected for color display to output the color as a color data, a memory device for storing the color data representative of the color designated, a memory controller responsive to receipt of an address issued from the selected coordinate data for controlling the color data to be written into and read out of the memory, and an output controller which allows the color data read from the memory to be supplied to the liquid crystal display panel as video data.
