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.
