Abstract
In a flat image display device in which a first substrate having phosphor layers formed on an inner surface thereof and a second substrate having electron emitting elements which excite the phosphor layers are located opposite each other with a gap therebetween, the plate thickness of the second substrate is made smaller than the plate thickness of the first substrate. The second substrate is formed thinner than the first substrate so that it is more flexible. Even if spacers are subject to variation in height, therefore, the first and second substrates can be securely brought into contact with the spacers, whereby gaps between the spacers and the substrates can be eliminated, and electric discharge between the first and second substrates can be restrained.
