PURPOSE: A backlight unit, a display apparatus using the same, and a lighting system including the same are provided to prevent the thermal deformation of an optical member by using an insulating part for blocking the heat of a light source. CONSTITUTION: At least one light source(100) is arranged between a first and a second reflecting part(200,300). A cover plate(500) supports the first reflecting body and the light source. An optical member(400) is supported by the cover plate and is separated from the second reflecting part. At least one insulating part(800) is formed between the cover plate and the optical member. |
