ABSTRACT:
The back light device for a liquid crystal display disclosed has a photoconductor, a light source, a reflection plate, and a pair of resin blocks. A case is placed at a back surface of the photoconductor for holding the reflection plate and fixing the photoconductor. In the case, a plurality of consecutive cutouts are provided at a portion that holds the reflection plate. The consecutive cutouts are perpendicular to an axis of the light source. This structure enables the dissipation of the heat accumulated in the reflection plate through the consecutive cutouts.
