<p>Provided are a light guide device which can be manufactured in a stacked structure in which layers are stacked, and can guide light from a light source provided on one side of a base material to the other side thereof, and provide various illumination display by using two kinds of light, and a method of manufacturing same. When the light emitted from a first light source (21) is made incident upon a coupling layer (6), the light is transmitted from a coupling surface (6f) of the coupling layer (6) to a base material sheet (1) and is applied to a first light guide layer (2) provided on the upper side of the base material sheet (1). Furthermore, the light from a second light source propagates within a second light guide layer (5) provided on the lower side of the base material sheet (1). The light emitted from a plurality of light sources provided on the lower side of the base material sheet (1) can be guided to separate optical paths on the upper and lower sides of the base material sheet (1).</p> |
