Liquid crystal display and its manufacturing method

摘要

With the liquid crystal display provided by the present invention, the display contrast is improved by suppressing the reflection of an external light by a light diffusing layer employed in the liquid crystal display. The liquid crystal display comprises a liquid crystal panel 1, a directional backlight 2 and a light diffusing means. The liquid crystal panel 1 is of the transmission type having a front face and a back face on the side opposite to the front face. A polarizing plate 4 is placed in front of the front face of the liquid crystal panel 1. The backlight 2 is placed on the back side of the liquid crystal panel 1, providing all but parallel incident illumination light beams to the liquid crystal panel 1. The light diffusing means is placed on the front side of the liquid crystal panel 1, diffusing and emitting the incident illumination light beams leaving the liquid crystal panel 1. The light diffusing means comprises a light diffusing layer 9 and transparent filler stuff 10. The light diffusing layer 9 is made up of transparent fine particles 9a spread all over the gap between the front face of the liquid crystal panel 1 and the polarizing plate 4. The transparent filler stuff 10 is used for filling up gaps among the transparent fine particles 9a. The transparent fine particles 9a each have a refraction index different from that of a glass plate 3 constituting the front face of the liquid crystal panel 1 while the transparent filler stuff 10 has a refraction index close to that of the glass plate 3. <MATH>
