Title: Liquid crystal display substrate
Inventor: MIZOKOSHI YASUO
IPC: G02F1/1345
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to fix a substrate to a stage with sufficient strength even in a vacuum apparatus by using an electrostatic chuck by forming a conductive thin film or semiconductor thin film on the surface on the side opposite to the surface to be formed with liquid crystal patterns. SOLUTION: The liquid crystal patterns 2 are formed on the one surface of the glass substrate 1 and an ITO(indium tin oxide) film (conductive thin film) 3 is formed over the entire part of the other surface (rear surface) opposite thereto. This liquid crystal display substrate is placed on the electrostatic chuck. When voltage is impressed on electrostatic chuck electrodes by an external power source in a state where the ITO film 3 is ground, a charge (plus polarity) is induced on the electrostatic chuck surface by the voltage impressed on the electrostatic chuck electrodes. The induced charge (minus charge) of the opposite polarity is generated in the ITO film 3 by this charge. Attraction force is, therefore, generated by the electrostatic force between the charge of the electrostatic chuck surface and the induced charge of the ITO film 3.
