ABSTRACT:
An image display apparatus includes an envelope, first to third electroconductive members disposed in the envelope, a plate-like spacer disposed between the first and third members and between the second and third members, and a circuit for supplying a potential to the first member and supplying a potential lower than that of the first member to the second and third members. When a sheet resistance between a first region of the spacer to which the potential is supplied from the first member and a second region of the spacer to which the potential is supplied from the second member is defined as ρf [Ω/□] and a sheet resistance between a third region of the spacer to which the potential is supplied from the third member and a region located between the first and second regions is defined as ρr [Ω/□], a condition 1/100<ρr/ρf≦40 is satisfied.
