  • Optical compensatory sheet producing method and apparatus, thermal treating method and apparatus, and dust removing method and apparatus
    Patent number: 7575773
    Abstract: An optical compensatory sheet producing apparatus produces an optical compensatory sheet having a liquid crystal layer. In the apparatus, a rubbing unit is supplied with resin film having a first layer including resin, and subjects the first layer to a rubbing process, so as to form an orientation layer. A dust remover removes dust from the orientation layer by use of liquid such as perfluorocarbon, to which the orientation layer is insoluble. A liquid crystal layer coater is disposed downstream from the dust remover, for coating the orientation layer with coating liquid including liquid crystalline compound, so that the liquid crystal layer is formed.
    Type: Grant
    Filed: March 17, 2006
    Date of Patent: August 18, 2009
    Assignee: FUJIFILM Corporation
