example

[0671] Hereinafter, the present invention will be described in more detail with examples, and the materials, usage amounts, proportions, processing contents, processing order, etc. shown therein can be appropriately changed as long as they do not depart from the gist of the present invention. Therefore, the scope of the present invention should not be limitedly interpreted by the examples shown below.

reference example 1

[0673] (1) Fabrication of transparent supports with rubbed alignment films (alignment films A to C)

[0674] (Formation of Alignment Film A)

[0675] On the surface of the transparent glass support, apply a 4% water / methanol solution of polyvinyl alcohol PVA103 manufactured by Kuraray (Kuraray) Co., Ltd. with a No. 12 rod (dissolve 4.0 g of PVA-103 in 72 g of water and 24 g of methanol, the viscosity 4.35cp, surface tension 44.8dyne), dried at 120°C for 2 minutes. Re(550) of the glass support was 0 nm, Rth=0 nm, and the alignment film thickness was 0.9 μm. Continue to perform a back-and-forth rubbing treatment in one direction at 1000 rpm to produce a glass support with a rubbed alignment film (alignment film A). This alignment film is generally used as a parallel alignment film.

[0676] (Formation of Alignment Film B)

[0677] In the same manner as above, the solution of the orthogonal alignment film (compound No. 5) was coated on the surface of the transparent glass sup...

reference example 2

[0688] An optical film was produced in the same manner as in Reference Example 1 except that the following rod-shaped liquid crystal composition 2 was used instead of the above-mentioned liquid crystal composition 1, and the obtained optical film was confirmed with a microscope.

[0689] · Rod-shaped liquid crystal composition 2

[0690] The following polymerizable liquid crystal 2: the above-mentioned polymerization initiator 1: MEK solution with a solid content of 26% of the above-mentioned air interface alignment agent 1 (=100:3:0.3)

Abstract

The present invention provides a laminate in which two or more types of alignment control layers are formed on a transparent support and can perform alignment control in a direction in which the major axes of liquid crystals are perpendicular to each other in a plane parallel to the alignment control plane. . The laminate is characterized in that it has a transparent support and a patterned alignment control layer on the transparent support. The patterned alignment control layer includes alignment control surfaces with different compositions and different alignment control capabilities. The first alignment control area and the second alignment control area, and the alignment control surfaces are arranged alternately. The respective alignment control planes of the first alignment control region and the second alignment control region can perform alignment control in directions in which long axes of liquid crystals are perpendicular to each other in a plane parallel to the alignment control plane.

Description

technical field [0001] The present invention relates to a laminate that can be used as a support for a patterned optical film, a method for manufacturing the laminate, an optical film, a polarizer, and an image display device using the laminate, especially a stereoscopic image display device. Background technique [0002] Conventionally, an optically anisotropic layer patterned into liquid crystal segments whose slow axes are perpendicular to each other has been provided as an optical film for a 3D image display device. A method for producing an optical film having such a patterned optically anisotropic layer is known, using a photo-alignment film that uses a photomask or the like to irradiate light from two directions so as to have different alignment control capabilities. The alignment process is performed in such a manner that regions are alternately formed (see Patent Document 1 and Non-Patent Document 1). [0003] Another method using a rubbed alignment film is also p...
