发明名称 Liquid crystal display device
摘要 The present invention provides a liquid crystal display device capable of achieving natural and high-quality color display without reddish color shift, not only when viewed in the normal direction but also when viewed obliquely. A liquid crystal display device 1 of the present invention includes a light diffuser plate 3, a light source 2 disposed on the back side of the light diffuser plate 3, and a liquid crystal panel 30 disposed on the front side of the light diffuser plate 3, wherein the light diffuser plate 3 is constituted by dispersing light diffusing particles in a transparent material, and the absolute value of a difference Deltan in the refractive index between the transparent material and the light diffusing particles and a 50% cumulative particle diameter D50 (mum) of the light diffusing particles satisfy a relation 0.01<=DeltanxD50<=0.25 or 0.61<=DeltanxD50<=0.75.
