A liquid crystal display device is provided with a backlight and a color filter. The backlight is provided with a white LED device wherein colors are mixed by combining a blue LED, a red light emitting phosphor and green light emitting phosphor. The color filter is provided with colored pixels of a plurality of colors, including a red pixel, on a transparent substrate. The emission spectrum of the white LED device has a first peak wavelength in a range of 440nm or more but not more than 470nm, a second peak wavelength within a range of 510nm or more but not more than 550nm, and a third peak wavelength within a range of 630nm or more but not more than 670nm. The red display chromaticity of the liquid crystal display device is within a chromaticity range formed by connecting the four points in an xy chromaticity coordinate system, which are points (0.620, 0.280), (0.620, 0.300), (0.680, 0.315) and (0.680, 0.280). |
