Abstract
(EN)
The present invention provides: a light emitting display device which is capable of reliably preventing interference patterns from becoming visible in a viewing area even if warping of a light guide plate has occurred; and a game machine. According to the present invention, a first light guide plate (11) and a second light guide plate (12) are arranged to face each other, and a viewing area of a surface of the second light guide plate (12), said surface facing the first light guide plate (11), is provided with a microprojection group that is composed of a plurality of microprojections (17). The plurality of microprojections (17) have such an arrangement and a height that ensure a distance, by which interference patterns are prevented from becoming visible, between the first light guide plate (11) and the second light guide plate (12) by coming into contact with the second light guide plate (12). In addition, the microprojection group and dimples (16), which are provided on the second light guide plate (12) so as to constitute a design part, are formed on the same surface.

La présente invention concerne : un dispositif d'affichage électroluminescent qui est susceptible d'empêcher de manière fiable que des figures d'interférence deviennent visibles dans une zone de visualisation même si un gauchissement d'une plaque de guidage de lumière s'est produit ; et une machine de jeu. Selon la présente invention, une première plaque de guidage de lumière (11) et une seconde plaque de guidage de lumière (12) sont agencées l'une en face de l'autre, et une zone de visualisation d'une surface de la seconde plaque de guidage de lumière (12), ladite surface faisant face à la première plaque de guidage de lumière (11), est pourvue d'un groupe de microsaillies qui est composé d'une pluralité de microsaillies (17). L'agencement et la hauteur de la pluralité de microsaillies (17) sont tels que, par entrée en contact avec la seconde plaque de guidage de lumière (12), celles-ci assurent l'existence, entre la première plaque de guidage de lumière (11) et la seconde plaque de guidage de lumière (12), d'une distance qui empêche que les figures d'interférence deviennent visibles. De plus, le groupe de microsaillies et des alvéoles (16), qui sont ménagées sur la seconde plaque de guidage de lumière (12) de façon à constituer une partie de conception, sont formées sur la même surface.
