Abstract
An image display apparatus includes a front substrate, and a rear substrate opposed to the front substrate. The front substrate has phosphor layers, resistor layers provided between the phosphor layers, a metal-back layer divided into metal-back segments covering the phosphor layers and resistor layers at least in part, and spaced apart by gaps Gx in a first direction intersecting at right angles with a scanning direction and by gaps Gy in a second direction identical to the scanning direction, and a voltage-applying portion which applies a voltage on the metal-back segments. Rx(100)/Rx(1)<Ry(100)/Ry(1) is satisfied, where Rx(V) is a resistance between any two metal-back segments on the sides of a gap Gx, respectively, which is the function of voltage V [V], and Rx(V) is a resistance between any two metal-back segments on the sides of a gap Gy, respectively, which is the function of the voltage V [V].
