IPC: H01J11/10
Filed: 1978-06-26
Abstract: PURPOSE: To obtain a display unit which has excellent discharge characteristics, i.e. starts accurate discharge over the entire surface in a short time.  
     CONSTITUTION: This unit has electrode holding plates 10 and 11 of transparent float plate glass, X-axial and Y-axial electrodes 12 and 13 arranged intersecting each other, dielectric layers 14 and 15 formed on the electrode surfaces, and insulating layer 17 with through hole 18 formed on the dielectric 14; through hole 18 provided to insulating layer 17 at the visual side prescribes a display region, and the direction of arrow 19 indicates the visual direction. Here, insulating layers 16 and 17 are formed by a screen-printing method, and insulating layer 17 is made thinner than layer 16. Further, since insulating layer 16 at the opposite side of the visual side is formed thick and in a prop shape, not only the space prescribed by through hole 18 but also almost all of the space between insulating layer 17 and dielectric layer 14 act as the discharge space.
