A light diffraction film includes a transparent substrate; and a light diffraction layer containing a binder resin and particles, in which an average primary particle diameter of the particles is 1 &#x3bc;m to 10 &#x3bc;m, and a coverage of a surface of the transparent substrate covered with the particles is 70% to 90%.

Light diffraction film and wearable display device

There is provided a liquid crystal display including: a liquid crystal cell in which a liquid crystal layer is installed between two glass substrates; polarizing plates on both surfaces of the liquid crystal cell; and a backlight at a rear side of the liquid crystal cell, which is a non-visual side, wherein in a polarizing plate at a front side of the liquid crystal cell, which is a visual side, a difference in a moisture content of the polarizing plate at the front side under a specific condition in elapse of time is 0.01% or more and 3.0% or less.

Liquid crystal display

A polarizer having at least one optical film and at least one polarizing film, wherein the absolute value of the photo-elastic coefficient C of the optical film is 2&#xd7;10Paor more, the optical film has an in-plane direction in which the sound propagation velocity is the maximum, and the angle between the in-plane direction in which the sound propagation velocity through the optical film is the maximum and the direction of the absorption axis of the polarizing film falls within a range of from 0&#xb0; to less than 45&#xb0;, is excellent in working aptitude and can prevent optical unevenness of the liquid-crystal display device accompanied by environmental changes.
