FIELD EMISSION DISPLAY

摘要

PURPOSE: A field emission display is provided to achieve improved luminance of screen and contrast ratio of screen by using the cathode electrode and barrier ribs as a black matrix. CONSTITUTION: A field emission display comprises a transparent front substrate(2); a rear substrate opposed to the front substrate with a predetermined spacing between the front and rear substrates; a cathode electrode(8) formed into a line pattern on the front substrate opposed to the rear substrate; an emitter(10) serving as a carbon-based plane electron source formed on the cathode electrode; an anode electrode(14) formed on the rear substrate opposed to the front substrate and made of a metal material having a high reflectivity; and a phosphor screen(16) formed on the anode electrode. The cathode electrode is made of a conductive material which is optically opaque, and serves as a black matrix.
