Abstract:
An image display apparatus includes a rear plate including electron emitting devices each including a pair of electrodes and an electron emitting unit, first wirings each interconnecting electrodes in one of the pair of electrodes of the electron emitting devices arrayed at the same row, second wirings each interconnecting electrodes in another of the pair of electrodes of the electron emitting devices arrayed at the same column and higher in resistance than the first wirings, an insulating layer covering the second wirings, and resistive films connected to the first wirings and partially overlapping with the second wirings to cover the insulating layer, and having surface resistance set to 108Ω/□ or more. The resistive films are connected to the first wirings at portions not overlapping with the second wirings, and a length L of the resistive film between a portion of the resistive film connected to the first wiring and a portion overlapping with the second wiring satisfies a relationship.
