LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device using a light emitting diode (LED) module as a light source for backlight. Storing sections (21a-21e) are provided at positions facing a light emitting diode module (25) on a light guide plate (21) constituting the backlight, and the light emitting diode module (25) is inserted into the storing sections (21a-21e). Furthermore, under a status where an insulating substrate (26) mounted with the light emitting diode module (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 is lengthened, and deterioration of light emitting efficiency can be suppressed.
