Abstract:
To improve the display quality of a liquid crystal display device (in particular, the downward viewing angle characteristics of the liquid crystal display screen).
The light diffusing film has a light diffusing layer containing light transmitting fine particles in a light-transmissive resin. The difference between the refractive index of the light-transmissive fine particles and the refractive index of the light-transmissive resin is ≥0.02 and ≤0.05.
