Patent ID: 7821191

Claim:
A field emission display comprising: an electron source; a substrate; a phosphor layer arranged on the substrate, and emitting light by irradiation with an electron emitted from the electron source; a metal back disposed on the substrate and supplied with a voltage for accelerating the electron; and a common electrode disposed on the substrate for supplying the voltage to the metal back, wherein the common electrode includes one and other electrode films disposed apart in a longitudinal direction of the common electrode, and includes a resistor film, wherein the one electrode film has an opposed portion opposing to the other electrode film, which is a part of a contour of the one electrode film, and the other electrode film has an opposed portion opposing to the one electrode film, which is a part of a contour of the other electrode film, and the resistor film connects the opposed portion of the one electrode films and the opposed portion of the other electrode film, and wherein a length of the opposed portion of the one electrode film is longer than a length of the one electrode film in a direction orthogonal to the longitudinal direction and a length of the opposed portion of the other electrode film is longer than a length of the other electrode film in the direction orthogonal to the longitudinal direction.
