An optical filter comprises a transparent support and a filter layer. The filter layer has an absorption peak in the wavelength range of 620 from 560 nm, and the full width at half maximum of the absorption peak ranges from 5 to 50 nm. This optical filter adequately absorbs undue light in an image display device (particularly, a plasma display panel).
