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.
