ABSTRACT:
A liquid crystal display device and manufacturing method thereof are provided where the liquid crystal display device is equipped with a light diffusion layer that gives sufficient light diffusion while providing easy control of the degree of diffusion of the transmitted light and which can be easily manufactured. The liquid crystal display device of the present invention includes a transmission type liquid crystal panel 1, a light diffuser 10 and a directional backlight 3. The liquid crystal panel 1 includes a pair of glass substrates 1, at the front surface of which the light diffuser 10 is provided. The light diffuser 10 that is characteristic to the present invention is divided up into a first resin layer 11B over which fine particles 8a are dispersed and a second resin layer 12. Since the refractive index of the first resin layer 11B is approximately the same as that of the fine particles 8a, there is no lens effect between the fine particles. This gives the same effect as if the fine particles 8a were put into a single row even if the fine particles 8a are actually overlaid. The visual field angle improving effect of the light diffusion means is therefore maintained while manufacturing is simplified.
