Image display device

An image display device comprising:

• an envelope having a first substrate formed with a phosphor screen and a second substrate which is located opposite the first substrate across a gap and on which a plurality of electron emission sources for electron emission toward the phosphor screen are located;
• a supporting substrate located between the first and second substrates and having a first surface opposed to the first substrate, a second surface opposed to the second substrate, and a plurality of electron beam apertures opposed to the electron emission sources;
• and
• a plurality of columnar spacers which are set up between the second surface of the supporting substrate and the second substrate and support an atmospheric pressure acting on the first and second substrates,
• the supporting substrate having a plurality of height reducing portions being individually in contact with the spacers and elastically deformable in the height direction of the spacers, each of the height reducing portions having a recess formed in the first surface so as to face the spacer, the electron beam apertures on the opposite sides of each spacer in each of the height reducing portions being larger than the other electron beam apertures.
