PROBLEM TO BE SOLVED: To prevent the occurrence of discharge by reducing concentration of an electric field on the end face of a high voltage-applied portion of a phosphor face in a flat type image display device. SOLUTION: The flat type image display device is equipped with the rear face substrate 1 having a plurality of signal wirings 8 on a glass substrate, the front face substrate 2 having a phosphor layer 15, a BM film 16, and a metal back 17 on the glass substrate, and a frame body 3 interposed between these rear face substrate 1 and the front face substrate 2. A high resistance film 18 is arranged to cover the peripheral edge 171 of the metal back 17, and furthermore, a spark prevention member 22 is arranged in contact with the terminating end 181 of this high resistance film 18.
