Disclosed is a silver halide photographic material which comprises at least one methine dye represented by the following formula (I):
1
wherein Y represents a furan ring or a pyrrole ring, and Y may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring, or may have a substituent; the bond between two carbon atoms in which Y is condensed may be a single bond or a double bond; Z represents an atomic group necessary to form a 5- or 6-membered nitrogen-containing heterocyclic ring, and Z may further be condensed with other 5- or 6-membered carbocyclic ring or heterocyclic ring; R represents a substituted or unsubstituted alkyl group, aryl group, or heterocyclic group; D represents a group necessary to form a methine dye; L
1
and L
2
each represents a methine group; p represents 0 or 1; M represents a counter ion; and m represents a number of 0 or higher necessary to neutralize the charge in the molecule.

An object of the present invention is to provide a method for manufacturing an optical laminate in which an alignment defect is less likely to occur in a light-absorbing anisotropic layer even in a case where a surface of a photo-alignment layer is rubbed; an optical laminate; and an image display device. The method for manufacturing an optical laminate according to an embodiment of the present invention is a method for manufacturing an optical laminate in which an optical laminate including a photo-alignment layer and a light-absorbing anisotropic layer and having a front transmittance of 60% or less is produced and which includes a photo-alignment layer formation step of forming a photo-alignment layer on a polymer film, and a light-absorbing anisotropic layer formation step of applying a liquid crystal composition containing a dichroic substance and a high-molecular liquid crystalline compound onto the photo-alignment layer to form a light-absorbing anisotropic layer.
