ABSTRACT:
The present invention relate to a liquid crystal display device using a light emitting diode (LED) module as a light source for backlight. Storing portions (21a-21e) are provided at positions facing a light emitting diode modules (25) on a light guide plate (21) constituting the backlight, and the light emitting diode modules (25) are inserted into the storing portions (21a-21e). Furthermore, under a status where an insulating substrate (26) mounted with the light emitting diode modules (25) is held by a holding plate (28), the holding plate (28) is removably attached to a heat sink substrate (27). The backlight has a structure wherein the light emitting diode module (25) can be replaced. Furthermore, since heat generated at the light emitting diode module (25) can be efficiently dissipated to the heat sink substrate (27), temperature increase of the light emitting diode module (25) is suppressed, and lifetime can be lengthened, and deterioration of luminous efficiency can be prevented.
