Patent abstract
An image display apparatus of smaller beam deviation is provided by making smaller the absolute value of an angle formed by an initial velocity vector of an electron emitted from the first electron-emitting devices closest to a spacer 100 and a line parallel to the longitudinal direction of a spacer 100, rather than the absolute value of an angle formed by an initial velocity vector of an electron emitted from the second electron-emitting devices secondary closer to the spacer 100 and the line parallel to the longitudinal direction of the spacer 100.
