Abstract
An image display apparatus includes first and second substrates, an electron emitting device, light emitting members, and a spacer located between the first and second substrates. Straight-line ribs higher than the light emitting members are formed on the second substrate with one of the lines of light emitting members interposed between each adjacent pair of ribs. The spacer extends in a second direction intersecting a first direction in which the ribs extend, and is located between the light emitting members adjacent to each other in the first direction. The ribs include first and second ribs, and each first rib includes a wide portion where it intersects the spacer, the wide portion having a large width in the second direction and being higher than parts of the second ribs intersecting the spacer, at least one of the second ribs being disposed between each adjacent pair of first ribs.
