PURPOSE: A field emission display device is provided to compensate deterioration of brightness by reducing area of black matrix film in a phosphor screen, while realizing easily a screen with high contrast and high resolution. CONSTITUTION: A field emission display device(2) comprises a front and a rear substrates(4,6), a cathode electrode(8), an insulating layer(10), a gate electrode(12a,12b), an emitter(16), an anode electrode(18), and a phosphor screen(24). The front and the rear substrates face each other to have an inner space. The cathode electrode is formed with a line pattern along a first direction on one surface of the rear substrate. The insulating layer is formed on the whole surface of the rear substrate by covering the cathode. The gate electrode is formed with a line pattern along a second direction intersecting vertically the first direction. The emitter is formed on the inside of a hole penetrating the gate electrode and the insulating layer at the intersecting area of the cathode electrode and the gate electrode. The anode electrode is formed on one surface of the front substrate. The phosphor screen includes R, G, and B phosphor films and a black matrix film surrounding the phosphor films.
