  • Patent number: 4891635
    Abstract: An electrostatic display element making use of electrostatic force acting between a movable electrode and a pair of fixed electrodes kept oppositely to each other with said movable electrode positioned therebetween. The movable electrode, which is made of a flexible film plated with thin metallic layers, is supported by a film holder consisting of two contact plates without using an electrically conductive adhesive for the purpose of preventing the movable electrode from being wrinkled owing to the use of the adhesive. To achieve a good electric contact between the movable elecrode and the film holder, at least one of said contact plates is made of electrically conductive elastomer.
