Abstract:
Provided is a cellulose acetate film used for optical compensation and, in particular, a cellulose acetate film having a low retardation value R th in the film thickness direction.
Abstract:
The present invention relates to a method for manufacturing a patterned optical retarder including a liquid crystal sheet where a phase delay layer pattern having a ?/4 wavelength is formed by forming an alignment layer patterned on an optical alignment layer by using a single alignment process. The method of the present invention for manufacturing an optical retarder has great effect in reducing the error rate of an existing method and in reducing processing costs because optical alignment is possible by means of a single process using a mask in the optical alignment process.
Abstract:
The present invention relates to a casting belt used for manufacturing an optical film by means of a solvent casting process, in more detail, a casting belt for producing a transcendental wide width film which is used to produce a film in a gel state by casting a dope when manufacturing a film that is used for a polarizer of liquid crystal displays or optical compensation films.
Abstract:
Provided are an optical film for use in flat panel display (FPD) devices, and a method for manufacturing the same. Particularly, there is provided a method for imparting surface roughness to an optical film, which includes forming dented craters having a radius of curvature of 10 nm-100 µm on the surface of an optical film obtained by a solution casting process and forming a plateau between one crater and another crater. There is also provided an optical film obtained by the same method.
Abstract:
The present invention relates to an apparatus for manufacturing an optical film and more particularly, an apparatus for manufacturing a cellulose acylate film using a teflon coated roller which includes the teflon coated roller having a fluorine resin coating layer formed on the outer peripheral surface thereof and a steam jet cylinder for steam jetting thereby efficiently eliminating curls generated upon the manufacture of a cellulose acylate film.
