[0336] [Preparation of Low Refractive Index Layer]

[0337] The low refractive index layer can be prepared by dissolving or dispersing a fluorine-containing antifouling agent having at least one polymerizable unsaturated group, a fluorine-containing copolymer having at least one polymerizable unsaturated group, inorganic fine particles, and any desired The ingredients prepare a coating liquid and apply it to a surface. Simultaneously with coating or after coating and drying, its crosslinking reaction or polymerization is performed under ionizing radiation such as light and electron beams or heat irradiation, thereby hardening.

[0338] Specifically, if the low-refractive index layer is prepared by cross-linking reaction or polymerization of ionizing radiation curable compounds, it is preferable to perform cross-linking or polymerization in an atmosphere having an oxygen concentration of 10 vol% or less. By forming the layer in an atmosphere having an oxygen concentration of 1...

[0390] 40 parts by mass of additive solution B was added to 477 parts by mass of cellulose acylate solution A and thoroughly stirred to prepare a dope. The paint was cast via a casting spout onto barrels cooled at 0 degrees Celsius. When the solvent content therein reached 70% by mass, the formed film was peeled off, and both sides in the width direction thereof were fixed with a pin tenter (described in JP-A4-1009 image 3 middle). When the solvent content in the film is 3% by mass to 5% by mass and the distance at the pin tenter is controlled so that the stretch ratio of the fil...

[0455] A patterned optically anisotropic layer B was fabricated in the same manner as in Example 1, except that the transparent support A was changed to the above-mentioned transparent support B, and the formula of the rubbing alignment layer coating liquid was changed to the following formula. The thickness of the alignment layer was 0.5 micrometers, and the thickness of the optically anisotropic layer was 0.9 micrometers.

Abstract

Disclosed is an optical film for 3D image display devices, comprising at least an optically-anisotropic layer formed of a composition that comprises, as the main ingredient thereof, a discotic liquid crystal having at least one polymerizable group, wherein: the optically-anisotropic layer is a patterned optically-anisotropic layer which comprises a first retardation domain and a second retardation domain differing from each other in at least one of the in-plane slow axis direction and retardation in-plane thereof and in which the first and second retardation domains are alternately arranged in plane.

Description

technical field [0001] The present invention relates to an optical film for a 3D image display, a 3D image display element and a 3D image display system, which have an optically anisotropic layer containing a high-definition directional pattern, are easy to manufacture, and have improved display performance without the problem of reduced brightness. Furthermore, light fastness is improved. Background technique [0002] A 3D image display device for displaying 3D images requires optical components for converting right-eye images and left-eye images into, for example, circularly polarized images in opposite directions. For example, as the optical member, a patterned retardation film in which a plurality of domains different from each other in the slow axis and retardation are regularly arranged in a plane is used. [0003] Hitherto, patterned optical compensation films formed by using liquid crystal compounds or the like have been proposed (for example, JP-A 2006-276849 and J...
