Patent attributes
A display device is capable of substantially reducing or preventing warping or deformation thereof by using a bimetallic effect. The display device includes a backlight unit including at least one light source; a light source circuit board at which the light source is disposed; a first heat dissipation plate configured to receive heat generated from the light source through the light source circuit board, and to discharge the heat; a bottom case configured to accommodate the light source, the light source circuit board, and the first heat dissipation plate; and a second heat dissipation plate configured to resist a deformation force that is applied to the first heat dissipation plate or the bottom case, the second heat dissipation plate has a thermal expansion coefficient different from a thermal expansion coefficient of the first heat dissipation plate.
