Provided are a backlight device and a liquid-crystal display device whereby, while carrying out a radiation countermeasure of a light source, uniformity of temperature of a back face chassis is effected. The backlight device comprises: a light-guide plate () which emits toward the front face side light which enters from an end face; a light source () which projects light toward the end face; a back face chassis () which is disposed on the back face side of the light-guide plate; and a heat radiation member () which is disposed on the back face side of the back face chassis, and which dissipates heat from the light source. The heat radiation member further comprises chassis contact portions (-) which make partial contact with the back face of the back face chassis at multiple sites.

Backlight device and liquid-crystal display device

Provided is a display device in which a panel module can be fixed to a front cabinet without using screws, and when performing maintenance, the panel module can be easily removed from the front cabinet. The display device including a panel module having a display surface on the front side thereof, a front cabinet surrounding a peripheral edge part of the panel module, and a back cabinet covering a back side of the panel module includes a flexible hook part protruded toward the back cabinet from the inner surface of the front cabinet, and an L-shaped fixing member which has an L shape and includes a latch plate having a hole part in which the flexible hook part is latched and a contact plate which contacts with a back surface of the panel module so as to fix the front cabinet to the panel module.
