The present invention relates to a method for manufacturing a patterned retarder including an optical alignment layer or a first domain optically aligned in a first direction and a second domain optically aligned in a second direction. According to the invention, it is possible to improve productivity and to maximize optical alignment efficiency by reducing an optical alignment processing time using polarized pulse UV.

Optical alignment method and patterned retarder manufacturing method using polarized pulse UV

An optical alignment device using pulse UV irradiates an alignment film with pulse UV to perform optical alignment of liquid crystal. The optical alignment device using pulse UV may include a chamber, a lamp which is installed at an upper portion of the chamber and emits pulse UV light, a stage which is provided at a lower portion of the chamber and on which a substrate having an alignment film formed on a surface thereof is placed, and a polarizer which is installed detachably between the stage and the lamp.

The present invention relates to an infrared blocking multi-layered insulating film having thermal anisotropy, the film comprising an infrared absorption layer comprising at least one of perovskite oxide dispersed sol, metallic oxide dispersed sol, and ITO or ATO; a thermal resistance layer located on or above one surface of the infrared absorption layer; and an emission layer located on or above another surface of the infrared absorption layer. An infrared blocking multi-layered insulating film having thermal anisotropy according to the present invention may control heat flow, thereby generating excellent insulating effect.

In a liquid crystal display, a first alignment layer formed on a first substrate includes a first region aligned in a first direction and a second region aligned in a second direction opposite to the first direction, and a second alignment layer formed on a second substrate facing the first substrate includes a third region aligned in a third direction different from the first direction and a fourth region aligned in a fourth direction opposite to the third direction. The liquid crystal molecules interposed between the first and second alignment layers are aligned in different directions in different domains defined by the first to fourth regions. A pixel electrode includes an extension part extending in at least one of the first to fourth directions. The aperture ratio and the light transmittance of the liquid crystal display are improved.
