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.

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

one or more luminescent sources,

a holder that is installed with the luminescent sources,

a housing that is installed with the holder, and

a supporting component made from an insulating material, having an insulator projection section such that the insulator projection section comes between an electrode section of the luminescent source and the holder.

13. The backlight apparatus as claimed in claim 12, wherein the insulator projection section is formed only in a position that faces the holder.
