1. A laminate comprising:
a near infrared light absorbing layer that includes a near infrared absorbing colorant;
a color filter layer that is arranged adjacent to the near infrared light absorbing layer in a thickness direction and includes a chromatic colorant; and
an oxygen barrier film that is formed on a laminate including the near infrared light absorbing layer and the color filter layer in this order,
wherein the near infrared absorbing colorant is a dye,
the near infrared absorbing colorant is at least one selected from the group consisting of a pyrrolopyrrole compound, a cyanine compound, and a squarylium compound,
the color filter layer includes a pigment as the chromatic colorant,
5 to 50 mass % of the chromatic colorant has a sulfo group bonded to a colorant skeleton,
the color filter layer includes colored pixels of multiple colors, and each of the colored pixels does not include the chromatic colorant in which an amino group is bonded to a colorant skeleton of the chromatic colorant or a colorant derivative in which an amino group is bonded to a colorant skeleton of the colorant derivative,
an oxygen permeability of the oxygen barrier film is 200 ml/m2·day·atm or lower,
the oxygen barrier film is formed at least one selected form the group consisting of SiO2, SiN, Al2O3, CaO, Fe2O3, MgO, GazO, ZrO2, TiO2, CaF2, tetraethoxysilane, tetraethyl orthotitanate, tetramethoxysilane, ethyltriethoxysilane, and methyl trimethoxysilane, and
the oxygen barrier film is an outmost layer interposed with a planarizing layer and a lens layer.
