PURPOSE:To heighten the degree of hardness of a game content and to improve interest ability by forming a non-polarizing part of arbitrary shape on a polarizing plate on one side out of a pair of polarizing plates, and arranging a polarizer provided with the same polarizing characteristic at the front of the non-polarizing part. CONSTITUTION:A notched part 27 (non-polarizing part) is formed at the upper side of an upper polarizing plate 7 located at the front side out of a pair of polarizing plates 7, 11 selected so as to intersect orthogonally their polarizing axes with each other. A liquid crystal cell 9 as a liquid crystal display plate on which a segment of arbitrary shape is formed in arranged between the upper polarizing plate 7 and the lower polarizing plate 11. The liquid crystal cell 9 is provided with transparent upper glass 29a and lower glass 29b, and liquid crystal is sealed in the inside. A pair of supporting plates 30a, 30b are fixed on the lower glass 29b, and the lower polarizing plate 11 and a reflection plate 13 are held between the pair of supporting plates 30a, 30b in a state where they are positioned. A game is progressed in a state where the whole display screen is displayed when the polarizer is used, and adversely, it is progressed in a state where part of the display screen is not displayed when no polarizer is used, therefore, the degree of hardness of the game content can be heightened. |
