Title:
ANISOTROPIC LIGHT DIFFUSION FILM LAMINATE AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2022157897
Kind Code:
A
Abstract:
To provide an anisotropic light diffusion film laminate having view angle dependency improvement effect better than the prior art for brightness and color changes due to angle of field.SOLUTION: An anisotropic light diffusion film laminate is formed by laminating at least two or more anisotropic light diffusion films with linear transmittance variable by an incidence angle of light, and comprises: one scattering center axis; a matrix region; and a plurality of columnar regions differing in refractive index from the matrix region. The plurality of columnar regions are oriented and extended from one front face to the other front face of the anisotropic light diffusion film. The plurality of anisotropic light diffusion films are laminated in a prescribed condition.SELECTED DRAWING: None
