Abstract

PURPOSE: To continuously change the resistance of a high resistance film, by coating a photo conductive film changing its electric resistance with light on an insulation substrate, forming the high resistance film on it selectively, providing an electrode band along the one side, and emitting movable light on the high resistance film and the electrode band via a slit.
