摘要： A front-illuminating device of the present invention, which is placed over the entire surface of an object to be illuminated such as a reflection-type liquid crystal display device when it is used, is provided with a light source and a light-directing body. The light-directing body has an incident surface on which light from the light source (light-source light) is made incident, a first light-releasing surface for releasing the light toward the object to be illuminated, and a second light-releasing surface which faces the first light-releasing surface and releases reflected light from the object to be illuminated. The second light-releasing surface is formed into a step shape in which slanting portions and flat portions are alternately placed. The light source light, released from the first light-releasing surface to the object to be illuminated, is reflected by the object to be illuminated and the reflected light is allowed to reach the observer from the first light-releasing surface through the flat portions. In this case, among the light-source light rays, the light components progressing in parallel with the flat portions are reflected by the slanting portions and directed to the object to be illuminated. Consequently, the present invention makes it possible to provide a brighter front-illuminating device in which the efficiency of use of the light-source light is improved.

摘要： A transparent substrate 2, into which light from a light source 9 is introduced through at least one side, includes a transparent first glass substrate (substrate body) 5a and a low refractive index layer 6 that is disposed on the first glass substrate 5a and has a lower refractive index than the first glass substrate 5a. Moreover, a high refractive index layer 7 having a higher refractive index than the low refractive index layer 6 is disposed on the low refractive index layer 6, thereby preventing the generation of light that leaks from the first glass substrate 5a to the outside through the low refractive index layer 6.

摘要： A backlight device includes a light diffusing member above a plurality of light sources that are partitioned into a plurality of illumination regions by a partition wall. A light incidence plane at which lights from the plurality of light sources enter is higher than the light sources and equal to or lower than a top of a partition wall. Moreover, a second light diffusing member is laminated above the light diffusing member so that a space is provided between the second light diffusing member and the first light diffusing member. The second light diffusing member has a light incidence plane in a position at a height that is higher than the top of the partition member. This makes it possible to independently control each of the illumination regions.

摘要： Featured are a front-illuminating device including a light source and first and second light-directing bodies. The first light-directing body is disposed in front of an object to be illuminated and has a first light-releasing surface from which light is released to the object to be illuminated and a second light-releasing surface, placed face to face with the first light-releasing surface, for releasing light reflected from the object to be illuminated. The second light-releasing surface also is formed into a step shape and includes slanting portions that reflect light mainly from the light source toward the first light-releasing surface. The second light-directing body is disposed between the first light-directing body and the object to be illuminated and is configured and arranged so a distance from each of the slanting portions to the surface of the second light-directing body second surface is essentially uniform.
