Light emission data is supplied to an RDATA latch 13R, a GDATA latch 13G, and a BDATA latch 13B and latched as R, G, and B data for every pixel. In an arithmetic operation processing unit 14, an arithmetic operation is performed using the latched R, G, and B data and a chromaticity correction coefficient Cij written in a chromaticity correction coefficient register 16. An arithmetic operation result of the arithmetic operation processing unit 14 is supplied as correction light emission data into a data memory 15 and stored. In a luminance correction data memory 20, luminance correction data is supplied to a constant current driver 18 in accordance with a supplied control signal. The constant current driver 18 drives an LED display 19 in accordance with the correction light emission data and the luminance correction data.
