Image display apparatus, manufacturing method of image display apparatus, and functional film

A functional film mounted on an image display apparatus including a first substrate having an electron-emitting device and a second substrate having an anode electrode that is opposed to the electron-emitting device,

• the functional film comprising a conductive layer that is provided on the side of a second face of the second substrate, the second face being an opposite face to a first face of the second substrate, the first face being located on the first substrate side,
• wherein
• a potential of the conductive layer is set to be lower than a potential of the anode electrode when displaying an image;
• and
• a surface resistance of the conductive layer is higher than a surface resistance of the anode electrode.

A manufacturing method of an image display apparatus comprising the steps of:

• preparing a display panel including a first substrate having an electron-emitting device and a second substrate having an anode electrode that is opposed to the electron-emitting device;
• and
• providing a conductive layer on the side of a second face of the second substrate, the second face being an opposite face to a first face of the second substrate, the first face being located on the first substrate side,
• wherein
• a potential of the conductive layer is set to be lower than a potential of the anode electrode when displaying an image;
• and
• a surface resistance of the conductive layer is higher than a surface resistance of the anode electrode.
