A liquid crystal display device is provided to minimize characteristic variation due to heat by preparing a heat dissipation hole in a lower cover and a reflective sheet and installing a filter unit in the heat dissipation hole of the lower cover or the reflective sheet. An optical source(102) supplies the light to a liquid crystal panel(101). A lower cover(103) receives the optical source and the liquid crystal panel and includes at least one first heat dissipation hole in one side. A reflective sheet(104) is prepared inside the lower cover and includes a second heat dissipation hole(104a) corresponding to the first heat dissipation hole(103a). |
