To provide a slim liquid crystal display unit having a large screen by providing a slim structure capable of sufficiently radiating the heat from a light source.
The liquid crystal display unit 1 includes: a liquid crystal panel 101; an light guide plate 121 installed on a rear face thereof; a pair of light source-mounted substrate 132 disposed opposing right and left side faces thereof; a light source 131 mounted on the light source-mounted substrate 132; a metal frame 133 connected on the opposite side to the light guide plate 121 of the light source-mounted substrate 132; a chassis member 111 for supporting the light guide plate 121 and a reflection sheet group 150; and a thermal diffusion member 161 fixed onto the metal frame 133 along with the chassis member 111. The chassis member 111 has a stepped portion 111a in the vicinity of the light source 131. Between the stepped portion 111a and the reflection sheet group 150, a thermal insulation member 112 is attached.
