Image display apparatus

A display apparatus comprising:

• a first insulating substrate provided with a cathode that emits an electron and a through hole;
• a second insulating substrate that faces a first face of the first insulating substrate and is provided with an anode to which a voltage for accelerating the electron is applied;
• a voltage application structure connected to the anode through the through hole, configured to apply the voltage to the anode;
• and
• a first potential regulation structure configured to enclose the through hole on the first face of the first insulating substrate and regulated at a lower potential than that of the anode,
• wherein the voltage application structure includes a second potential regulation structure that is in contact with a wall surface constituting the through hole therein and regulates a potential of a contact portion with the wall surface at a voltage same as that of a voltage application structure.
