摘要:
A display apparatus comprises: a rear plate which has an electron-emitting device; a face plate which has an anode electrode and a potential defining electrode; and a plate spacer which is opposite to the anode electrode and the potential defining electrode, between the rear plate and the face plate. An insulative base member of the spacer has a recessed portion which opposes to the anode electrode, the potential defining electrode, and a portion of the face plate between the anode electrode and the potential defining electrode. Thus, electric discharges between the spacer and the anode electrode and between the spacer and the potential defining electrode can be suppressed.
