ABSTRACT:
The present invention provides an incident light supply device which enables the intensity of illumination of an edge light illuminator to be drastically increased, while keeping it thin and reducing power consumption. An edge light panel is provided with a mirror frame at the incident end surface side. A reflection mirror is positioned at an angle to the edge light panel, and spaced away from a linear form light source in the thickness direction, whereby a pseudo-light source that is a virtual image of the linear form light source is obtained. This pseudo-light source is used together with the linear form light source as an incident light source. Between the edge light panels there is a spacing zone, to which the linear form light source is opposed in planar alignment. The location of the reflection mirror is determined such that the pseudo-light source is opposed in planar alignment with the incident end surface of each edge light panel. The pseudo-light source produced by the reflected image, has 95% of the reflectivity of the linear form light source. Thus, the intensity of illumination of the edge light illuminator arrangement can be drastically increased by a factor of for example, 2 or 3.
