There is provided a near infrared ray absorption composition which is well suited for use as a near infrared ray absorption filter particularly for a plasma display panel, since the composition is high in transmittance for visible rays, particularly blue ray transmittance and absorption efficiency for near infrared rays and besides, is excellent in long-term durability. The composition comprises a transparent resin; at least one dithiol nickel compound represented by the formula (1) wherein R1 to R6 are each a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, and may be the same or different; and/or at least one diimmonium compound represented by the formula (2) wherein R7 to R14 are each a hydrogen atom or an alkyl group having 1 to 8 carbon atoms or an aryl group having 6 to 24 carbon atoms, and may be the same or different.
