<P>PROBLEM TO BE SOLVED: To make the deflection pattern (dot pattern) of a liquid crystal display device invisible or inconspicuous even if it is visible even when the visual field angle of a player changes, in a game machine provided with a middle or large sized liquid crystal display device. Ž<P>SOLUTION: The liquid crystal display device 5 provided in a Pachinko slot machine 1 includes a liquid crystal panel 62 provided with pattern display areas 21C, 21L and 21R, a light guide plate 64 for supplying back light, a cold cathode tube 77, a reflection sheet 68, and a diffusion sheet 63 and a prism sheet 78 having openings 63a and 78a. On the back surface of the light guide plate 64, a dot print part 66 where the dot patterns 65a and 65b are formed and a dot non-print part 67 where the dot patterns 65a and 65b are not formed are provided. The dimension K1 of the openings 63a and 78a of the diffusion sheet 63 and the prism sheet 78 is formed to be smaller than the dimension K2 of the dot non-print part 67 (opening 64a).
