Abstract
To provide a thin liquid crystal display device featuring excellent color reproducibility. The liquid crystal display panel includes: a liquid crystal display panel outputting different colors on a per-pixel basis; and a backlight. The backlight includes: a light source; a light guide; a reflective sheet on a back side of the light guide; and a group of optical sheets including a wavelength converter and disposed between the liquid crystal display panel and the light guide. The wavelength converter has a structure where quantum dots are dispersed in a transparent medium. The wavelength converter is bonded to another optical medium by means of a diffusing adhesive. Nanoparticles for developing Rayleigh scattering are dispersed in the wavelength converter.
