Document Type and Number:
Japanese Patent JP5079889
Kind Code:
B2
Abstract:
A backlight unit 12 includes a chassis 14, a plurality of cold cathode tubes 18, an optical member 16 and a plurality of support members 20. The chassis 14 has an opening on a light exit side. The cold cathode tubes 18 are light sources arranged in a parallel layout and housed in the chassis 14. The optical member 16 is arranged on the light exit side outer than the cold cathode tubes 18 so as to cover the opening of the chassis 14. The support members 20 are arranged in a parallel layout along a parallel arrangement direction of the cold cathode tubes 18. The support members 20 are formed such that support positions of the optical member 16 are relatively closer to the cold cathode tubes 18 around the center and relatively farter from the cold cathode tubes 18 near the edges. The cold cathode tubes 18 are arranged at relatively smaller intervals around the center and at relatively larger intervals near the edges.
