    Abstract: Disclosed is a backlight device which is used for a color liquid crystal display and includes a light source and a backlight housing (23). The light source includes a red light emitting diode (21R), radiating red light, having a peak wavelength λpr such that 625 nm≦λpr≦685 nm, a green light emitting diode (21G), radiating green light, having a peak wavelength λpg such that 505 nm≦λpg≦540 nm, and a blue light emitting diode (21B), radiating blue light, having a peak wavelength λpb such that 420 nm≦λpb≦465 nm. The backlight housing mixes the red light, the green light and the blue light, radiated from the light source, to generate white light. A light emission intensity is adjusted so that a half value width of a spectrum of the red light, a half value width of a spectrum of the green light and a half value width of a spectrum of the blue light are such that 20 nm≦hwr≦25 nm, 30 nm≦hwg≦40 nm and 25 nm≦hwb≦30 nm, respectively.

    Abstract: Disclosed is a color liquid crystal display (LCD) apparatus employing a transmissive color liquid crystal display panel. The apparatus includes, as a light source, a main white light source (21) having a three wavelength phosphorescent lamp emitting light with three or more wavelengths, and an auxiliary light source (22) having at least one of a red light emitting diode (22R), a green light emitting diode (22G) and a blue light emitting diode (22B). The red light emitting diode emits red light with a peak wavelength λpr=645 nm, the green light emitting diode emits green light with a peak wavelength λpg=555 nm and the blue light emitting diode emits blue light with a peak wavelength λpb=440 nm. The light sources act for completely covering the color reproducing range of the sRGB standard and further enlarging respective color ranges.
