Abstract

The present invention provides a reflective sheet for improving display quality, a backlight unit including the reflective sheet, and a display device including the backlight unit. The reflective sheet includes a reflective layer and a heat dissipation layer. The reflective layer reflects light provided from the light source. The heat dissipation layer is in contact with the reflection layer to dissipate heat generated from the light source. The heat dissipation layer insulates the light source from the accommodating member to suppress leakage current of the power supply.

Description

[0001] Based on 35 U.S.C. §119, this application claims priority to Korean Patent Application No. 2004-93654 filed on November 16, 2004, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a reflective sheet, a backlight assembly with the reflective sheet, and a display device with the backlight assembly. More specifically, the present invention relates to a reflective sheet capable of improving display quality, a backlight assembly with the reflective sheet, and a display device with the backlight assembly. Background technique [0003] Display devices for displaying images have been widely developed. Liquid crystal display devices have advantages such as light weight, thin thickness, and low power consumption. Accordingly, liquid crystal display devices are widely used in various applications. [0004] A liquid crystal display device includes a backlight assembly and a liquid crystal display panel. The bac...
