Embodiment

[0083] A description will be given of Examples 1 and 2 of the brightness enhancement film 33 of the above-described embodiment in comparison with Comparative Examples 1, 2, and 3. In Examples 1 and 2 and Comparative Examples 2 and 3, the rod-shaped liquid crystal monomer was contained in the composition 110 used in the manufacturing process. In Example 1 and Comparative Example 2, a high Δn type was used as the rod-shaped liquid crystal monomer. In Example 2 and Comparative Example 3, a low Δn type was used as the rod-shaped liquid crystal monomer. In Comparative Example 1, instead of rod-shaped liquid crystal monomers, photocurable acrylic monomers were included in the composition 110 . In addition, in these Examples and Comparative Example 1, the pressing direction in the manufacturing process is the alignment direction of the protrusions 100 a of the substrate 100 (or the protrusions of the temperature regulation roller 250 ). In Comparative Example 2, the pressing direct...

Abstract

An optical film capable of improving luminance of a display unit, in which a viewing angle in the horizontal direction of emitted light of the display unit is wider than a viewing angle in the vertical direction and the emitted light of the display unit has a polarization component in the vertical direction viewable by polarized sunglasses, an illumination system including the same, and a display unit including the same are provided. The optical film includes a plurality of three-dimensional structures extending in one direction and arranged sequentially in a direction crossing the one direction. The three-dimensional structures contain a liquid crystalline polymer having orientation, and have refractive index anisotropy in which refractive index in the extending direction of the three-dimensional structures is smaller than refractive index in the direction crossing the extending direction of the three-dimensional structures.

Description

[0001] References to related applications [0002] This application contains subject-matter of Japanese Priority Patent Application JP 2008-200671 filed in the Japan Patent Office on Aug. 4, 2008, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an optical film having refractive index anisotropy, a manufacturing method thereof, and a display unit including the optical film having refractive index anisotropy. Background technique [0004] Over the years, cathode ray tubes (CRTs), which have been the mainstream of displays in the past, have been replaced by liquid crystal displays due to the advantages of low power consumption, space-saving characteristics, and low cost of liquid crystal displays. [0005] There are various types of liquid crystal displays when classified by, for example, an illumination method at the time of displaying an image. Representative examples include a transmissive liquid cry...
