Abstract
A structure of a vacuum display device is mainly constructed in a vacuum chamber, which is formed by the enclosure of a surface plate, a base plate, and a spacer plate. The surface plate includes a display matrix and a black matrix, the base plate includes an inner surface and an outer surface, while the spacer plate possesses a plurality of recesses in its edges. The required electrode lead wires are disposed on the inner surface of the base plate and are extended out through the recesses. A plurality of fins are disposed on the spacer plates to support the surface plate, the base plate, and the spacer plate, and are located at the black matrices. Additionally, sealing material is used to seal the connections between the surface plate, the base plate, and the spacer plate, and is also used to fill the gaps in the recesses.
