However, since the cloth-pasted partition completely shields the light, the space becomes dark and the psychological pressure action is large. Further, although the one using the etching glass has the effect of keeping the space bright, it has no complete shielding effect, and thus has a problem that it is inferior to the original function as a partition for obtaining spatial shielding. Such a problem occurs not only in partitions but also in other objects requiring shielding. For example, to incorporate decorative elements and to make the space look wider,
If the stairs are to be made of glass, optical shielding from below becomes a problem due to the nature of the stairs.

According to the present invention, light from a light source is introduced into the inside of the light guide plate from the end face of the substantially transparent light guide plate subjected to the light scattering treatment, and the light is diffusely reflected inside the light guide plate, whereby the light guide plate is made to have a surface. Flash. When the light guide plate emits surface light in this manner, light transmitted through the light guide plate relatively decreases, and the human image is focused on the light emitting surface, so that the optical image on the other side of the light guide plate is almost invisible. Thus, the light guide plate functions as an optical shield. In addition, since the light guide plate itself emits surface light, it has an effect of brightening the space in which the light guide plate is placed.
