Zusammenfassung: | A light source device that supplies light in a specific polarization direction to an information display device includes a point-shaped or planar light source, an optical means for reducing the divergence angle of light from the light source, and a light guide having a reflection surface that reflects light from the light source to propagate to the information display device. The reflection surface of the light guide is arranged so as to face the information display device, and reflects specific polarized image light displayed on the information display device to be displayed on the window glass, which is an information display surface. Therefore, an information display system is realized in which the inside of the window glass can be visually recognized from the outside or the outside of the window glass can be visually recognized from the inside when image information is not displayed. |
