(substrate)
Although it does not specifically limit as a board | substrate of this invention, It is preferable that it is a board | substrate which has a favorable surface property, a contact angle characteristic, and a water absorption characteristic. Examples of the base material for forming such a substrate include inorganic materials such as glass and polymer materials. As the polymer material, triacetate resins, acrylic resins, polyester resins, polycarbonate resins, polyethylene terephthalate resin, triacetyl cellulose resin, norbornene resin, cyclic Po Li olefin resin, polyimide resin, urethane Examples thereof include resins. These may be used alone or in combination of two or more. In particular, it is preferable to include a base material containing a polymer material.
The water absorption rate of the substrate is usually 5% or less, preferably 3% or less, more preferably 1% or less. By water absorption is not excessively large, since the substrate in forming a film of anisotropic materials by a wet film-forming method to suppress moisture absorption, coating defects due to warping of the substrate tends to hardly occur. In addition, since the swelling of the substrate after the formation of the optical film having anisotropy by the coating method can be suppressed, there is a tendency that optical defects do not easily occur. The “water absorption rate” in the present embodiment is
It is the value which measured the rate of weight change when immersed in 23 degreeC water for 4 hours using the test method of ASTMD570.

(Method for applying optical film having anisotropy)
The coating method of the optical film having anisotropy of the present invention is not particularly limited as long as it is a continuous coating. In the present invention, the term “continuous application” refers to the continuous application of regions to be a plurality of patterns (sections), not intermittent application for each pattern. Even when multiple patterns are provided on the substrate,
It can be applied continuously at one time, and it is not necessary to apply it separately for a plurality of patterns.
A method for continuously applying an optical film-forming composition having anisotropy to form an optical film having anisotropy is not particularly limited. For example, Yuji Harasaki "Coating Engineering"
(Asakura Shoten Co., Ltd., published on March 20, 1971) The method described on pages 253-277, supervised by Kunihiro Ichimura, “Creation and Application of Molecular Coordinating Materials” (CMC Publishing Co., Ltd., March 3, 1998) Issue) Method described on pages 118 to 149, slot die coating method, spin coating method,
Examples of the coating method include a spray coating method, a bar coating method, a roll coating method, a blade coating method, a curtain coating method, a fountain method, and a dip method. Among these, slot die coating is preferred because of the tendency of the optical film is obtained having a high anisotropy uniform.

(Process (II))
The present invention, as the step (II), on the optical film having anisotropy insolubilized in the step (I),
It has the process of apply | coating the photosensitive resin composition continuously and forming a protective layer.
(Protective layer)
The protective layer of the present invention is formed for the purpose of protecting the optical film having anisotropy from the subsequent process or stimulation or impact after the device is formed, but at the same time, the optical film having anisotropy is unnecessary. It also serves as a resist for patterning by removing portions.
The protective layer of the present invention is not particularly limited as long as it is formed by continuously applying a photosensitive resin composition on an optical film having anisotropy, but the protective layer has no optical anisotropy. It is preferable because it does not impair the performance of the optical film having anisotropy. The optical anisotropy of the present invention, anisotropy in electromagnetism properties at any two directions selected from a total of three directions in-plane two directions of the three-dimensional coordinate system in which the thickness direction and any Cartesian protective layer Is to have.
Since the protective layer of the present invention does not impair the optical properties of the optical film having anisotropy, the light transmittance at 550 nm at a thickness of 500 nm of the protective layer is preferably 80% or more, more preferably 85% or more. Yes, particularly preferably 90% or more. There is no particular upper limit, and a higher one is preferable.
