A screen display device is provided with address decoder 15, address generator 16, address translation circuit 17, data buffer 18 and data translation circuit 19 and is designed to reduce a rewrite operation time by rewriting data with a plurality of addresses of display memory 4 to the same data by the instruction of CPU 1. Further, it is possible to perform rewriting of the display characters, i.e. rewriting of display memory data efficiently and at a high speed.
