PROBLEM TO BE SOLVED: To obtain satisfactorily easy-to-see display information by pouring fluid plastic into a forming tool having mat surface structure and cooling it and taking out it so as to reduce light reflection. SOLUTION: Planes 24a and 24b are pressed together with high pressure by forming blocks 20 and 21 to form a forming space for a display window 12a by the plane 24a. A high-temperature and fluid acrylic material is force- fitted into a forming space through a pipe 22 by high pressure to respectively form the rear side of the window 12a with the plain 24a and the front side with a forming space within the block 21. The mat surface 21a formed by the block 21 by electric corruption is copied to the front side of the window 12a. After the acrylic material is cooled, the blocks are mutually separated and the integrally formed display window 12a is ejected from the molding block.
