表示機。[Claims for Utility Model Registration] (1) In a light display device that displays light from a light source on a viewing side through a front lens plate, the front lens plate collects light from the light source on a light incident side. A light diffusing lens is formed on the light emitting side to diffuse the light toward the observation side, an optical axis correction lens is formed on the light emitting part on the light emitting side to direct the light from the light diffusing lens to a predetermined position on the observation side, and a light axis correction lens is formed on the non-light emitting part on the light emitting side. A light display device characterized in that it is configured to form a prominent light absorption band that absorbs external light. (2) The optical display according to claim (1), wherein the light diffusion lens is a lenticular lens or a fly's eye lens, and the optical axis correction lens is a linear Fresnel lens or a prism lens. Machine.
