| 1. An image display apparatus comprising:
a first substrate carrying electron-emitting devices arranged in a matrix;
a second substrate being opposed to the first substrate, and having a plurality of anode segments, a common electrode, a resistor
connecting each of the plurality of anode segments to the common electrode, a light-emitting body emitting light in response
to an irradiation with electrons emitted from the electron-emitting devices, and carrying the common electrode along the edge
of the second substrate and the plurality of anode segments, wherein the plurality of anode segments include anode segments
which are placed next to each other and are connected to the same common electrode, wherein a constant voltage is applied
to each of said plurality of anode segments; and a plurality of spacers placed between the first and second substrates,
wherein a power consumption of at least one of the spacers is 0.1 W or less per each area of 1 cm2.
