A liquid crystal display apparatus employing a light source color switching system is provided for full color display. This apparatus improves display characteristics by securing a sufficient writing time and preventing afterimage phenomenon caused by residual charges. In the apparatus, while all the picture elements in displaying portion 14 are displaying the preceding color according to image signals for the preceding display color transmitted to liquid crystal capacitors 5 and additional capacitors 4, subsequent image signals are stored concurrently in a memory capacitors 2 through first TFTs 1 with second TFTs 3 turned off. Then, reset TFTs 6 are turned on to reset the image signals for the preceding display color held in liquid crystal capacitor 5 and additional capacitor 4. Then the second TFTs 3 on all the picture elements in displaying portion 14 are turned on to transmit the image signals stored in the memory capacitors 2 to additional capacitors 4 and liquid crystal capacitor 5 to display the subsequent color.
