Abstract
A liquid crystal display device, in which a backlight unit, a light conversion member, a selective reflection member, a liquid crystal cell, and a display-side polarizer are disposed in this order, the backlight unit includes a light source that emits unpolarized light having a light emission central wavelength in a wavelength range of 300 nm to lower than 430 nm, the selective reflection member reflects 60% to 100% of the unpolarized light entering the selective reflection member and transmits at least some of light in a wavelength of higher than 430 nm to 650 nm, and the light conversion member includes an aligned fluorescent material that emits blue, green and red light which are linearly polarized in a vibration direction parallel to an absorption axis of the display-side polarizer, is improved in terms of the front surface luminance.
