Abstract: The invention is intended to provide a lighting device that shortens time required to obtain peak brightness. A backlight unit 16 according to the invention includes: cold cathode tubes 22 as a light source; a chassis 18 housing the cold cathode tubes 22; a reflection sheet 21 disposed within the chassis 18 and reflecting light; and a heat insulator 27 disposed between the chassis 18 and the reflection sheet 21. Because the heat insulator 27 is disposes between the chassis 18 and the reflection sheet 21, heat in the chassis 18 is less likely to escape to the outside. Therefore, the temperature inside the chassis 18 can be efficiently increased with the heat generated by the cold cathode tubes 22.

Abstract translation: 本发明旨在提供一种缩短获得峰值亮度所需时间的照明装置。 根据本发明的背光单元16包括：作为光源的冷阴极管22; 容纳冷阴极管22的底架18; 设置在底架18内并反射光的反射片21; 以及布置在底架18和反射片21之间的隔热件27.由于隔热件27配置在底架18和反射片21之间，因此底架18中的热量不太可能逸出到外部。 因此，能够通过冷阴极管22产生的热量有效地提高底架18内的温度。
