Abstract:
1. An image display apparatus comprising: a first substrate and a second substrate facing each other and forming a hermetic container in which pressure is reduced; an electron emitting device disposed on an inner surface of the first substrate; a plurality of light emitting members arranged in a matrix arrangement comprised of a plurality of rows and a plurality of columns on an inner surface of the second substrate, and configured to emit light when irradiated with electrons emitted from the electron emitting device; a spacer located between the first and second substrates and supporting the hermetic container from the inside; and a plurality of straight-line ribs higher than the light emitting members are formed on the second substrate each of which is located along a column direction of the matrix arrangement, wherein the spacer extends in a row direction intersecting the column direction, and is located between adjacent two of the light emitting members in the column direction, and wherein the ribs include two or more first ribs and one or more second ribs, and each first rib includes a wide portion in a part where the first rib intersects the spacer, the wide portion having a large width in the row direction and being higher than parts of the second ribs in which the second ribs intersect the spacer, at least one of the second ribs being disposed between each adjacent pair of first ribs.
