Abstract

Dissipation of heat generated by a luminescent source, such as a fluorescent lamp, of a backlight apparatus and an LCD therewith is enhanced by providing a proximity section in a holder, making the hottest part the closest to the holder for efficient heat conduction.

Claims (4)

1. A backlight apparatus of an edge light type, comprising:

a plurality of straight luminescent sources;

a holder for holding said straight luminescent sources and having a heat-dissipating function, said holder having a shape being tapered such that a distance between the holder and the straight luminescent sources decreases toward each end of the straight luminescent sources, in a longitudinal direction, with the distance being maximum at center positions of the straight luminescent sources in the longitudinal direction; and

a light guide for directing light generated by said luminescent sources.
