Abstract

PURPOSE: To change the resistance of a resistive element in stepless, by coating the photo conductive film changing its electric resistance with light on an insulation substrate, providing a high resistance film on it selectively, constituting a resistive element through formation of the electrode band at the both sides with spacing, and changing the amount of light while emitting light on the entire surface.
