An optical filter comprises a transparent support and a filter layer. The filter layer has an absorption maximum in the wavelength region of 560 to 620 nm. The absorption maximum has a half-width in the range of 5 to 50 nm. The optical filter properly absorbs undesired light component emitted from an image display apparatus (especially, a plasma display panel).
