PROBLEM TO BE SOLVED: To provide a liquid crystal display device which can be made thin and has an improved thermal exhaustion property.SOLUTION: The liquid crystal display device includes: a backlight including a light sources illuminating a liquid crystal panel from back; and a chassis holding the backlight. The backlight includes: a plurality of light source units each including a combination of a LED emitting light in a direction parallel to a display surface of the liquid crystal panel, a wiring board mounted with the LED, and a light guide plate having translucency for guiding the light from the LED toward the liquid crystal panel; a metal chassis supporting the light-source units; and a heat sink sheet tightly inserted between the metal chassis and a surface opposite to a surface of the wiring board whereon the LED is mounted. A wiring pattern is formed on the opposite surface of the wiring board, and the wiring pattern formed within a predetermined distance from an outer periphery of the LED and the metal chassis are connected through the heat sink sheet. |
