Patent ID: 7977859

Claim:
An image display apparatus, comprising a display panel having a cathode plate and a phosphor plate, and a drive circuit, wherein the cathode plate comprises a plurality of electron emission elements, a plurality of scan lines mutually in parallel, and a plurality of data lines mutually in parallel and orthogonal to the scan lines, the electron emission element is a thin film electron emitter, in which a top electrode, an electron acceleration layer, and a base electrode are laminated, and a part of the top electrode constitutes an electron emission region, and by applying a voltage between the top electrode and the base electrode, electrons accelerated in the electron acceleration layer are emitted from the electron emission region, the cathode plate comprises a plurality of deflection electrodes, and has a center line at a position dividing a distance between the inner edges of adjacent the deflection electrodes in two equal parts, the electron emission region is disposed so as not to include the center line, the phosphor plate comprises a phosphor and an acceleration electrode, and is constituted so as to display an image by allowing the emitted electrons to excite the phosphor to emit light, the phosphor plate comprises a phosphor region in which the phosphor is patterned, and a center line of the phosphor region and a center line of the electron emission region are disposed to be shifted to each other.
