ABSTRACT:
The liquid crystal display device with a simple configuration is capable of emitting light with a desired color temperature, achieving high light use efficiency, and displaying high quality images. The liquid crystal display device includes a planar lighting device and a liquid crystal display panel. The planar lighting device includes a light source having LED chips for emitting blue light, a transparent light guide plate having a light entrance plane admitting light emitted by the light source and a light exit plane emitting planar light, and a fluorescent member disposed between the light emission plane and the light entrance plane and having one or more fluorescent substance coated areas for emitting white light by converting blue light from the light source into white light and one or more blue light passing areas passing blue light as blue light. The liquid crystal display panel essentially includes red, green and blue filters.
