Patent ID: 7537503

Claim:
A method for manufacturing a spacer having a high-resistance film covering a surface of a base material, that is inserted between a first substrate having electron emitting elements and a first conductive member, and a second substrate having a second conductive member set to a potential different from a potential of the first conductive member in a state of contacting the first conductive member and the second conductive member, and electrically connects the first conductive member and the second conductive member via the high-resistance film, said method comprising: a step of forming the high-resistance film according to a film forming step that includes a step of performing film formation from a direction of a first facing surface that faces the first conductive member, and a step of performing film formation from a direction of a side surface adjacent to the electron emitting element, wherein said film forming step is a step of forming the high-resistance film in which, when a sheet resistance value of the high-resistance film on the first facing surface is represented by R 1 , and a sheet resistance value of the high-resistance film on the side surface is represented by R 2 , R 2 /R 1 is 2-200.
