[0176] (Preparation method of optical compensation element)

[0177] The preparation method of the optical compensation element of the present invention includes a process of laminating multilayers in regular order on or over a support, the multilayers each including one or more inorganic materials and having different refractive indices to obtain the first optical properties. and polymerizing a polymerizable liquid crystal compound having a liquid crystal structure while maintaining the orientation of the liquid crystal structure to obtain a second optically anisotropic layer. The method may also include any other processes as required.

[0178] The optical compensation element can be produced by directly forming the first optically anisotropic layer on the surface of the support and forming the second optically anisotropic layer on or over the first optically anisotropic layer, or by forming the first optically anisotropic layer on the surface of the support Forming the sec...

[0251] A coating composition for an alignment layer having the following composition was used at 100ml / m 2 The amount of was added dropwise on the glass substrate and spin-coated at 1000rpm. Then, the coating composition for the alignment layer was dried with hot air at 100° C. for 3 minutes to form an alignment layer with a thickness of 600 nm. The alignment layer is rubbed to produce an alignment layer A aligned in a predetermined alignment direction.

Description

technical field [0001] The invention relates to an optical compensation element and a preparation method of the optical compensation element. The present invention also relates to a liquid crystal display device and a liquid crystal projector using the optical compensation element. Background technique [0002] Liquid crystal display devices (LCDs) have been continuously developed and are typically used in monitors for mobile phones, personal computers, televisions, and liquid crystal projectors. [0003] In these liquid crystal display devices, liquid crystals electrically control light passing through the liquid crystals to display light and dark levels on the screen, thereby displaying characters and / or images. Examples of modes in which liquid crystals are operated are twisted nematic (TN) mode, vertical alignment (VA) mode, in-plane switching (IPS) mode, optically compensated bend (OCB) mode, and electrically controlled birefringence (ECB) mode.
