The optical filter of Comparative Example 1 does not have a maximum absorption wavelength at a specific wavelength (380 to 500 nm) and has a large half width, and therefore, there is a possibility of absorbing light which is unnecessary. It is clear from this that the optical filters of Examples 1 to 16 using the phthalocyanine compound of the present invention have a steep absorption peak (half width of 50 nm or less) at a specific wavelength (380 to 500 nm). The image display device, particularly the optical filter for a plasma display, is excellent in performance.
