  摘要：

  This invention aims to provide a dichroic dye compound with high dichroic ratio in the wavelength range of 390 to 550 nm, which can be used to produce a light-absorbing anisotropic film, as well as colored compositions, light-absorbing anisotropic films, laminates, and image display devices. The solution is a dichroic dye compound with a structure represented by the following formula (I). In formula (I), X1 and X2 each independently represent a substituent group, m and n each independently represent an integer from 0 to 2. Ar1 and Ar3 each independently represent an aromatic hydrocarbon ring or an aromatic fused ring, and Ar2 represents an aromatic fused ring in which two hetero 5-membered rings, which may have substituent groups, are fused. At least one of L1 and L2 represents any of the connecting groups selected from −CH=CH−, −CH=N−, and −N=CH−.
