Color conversion composition, color conversion film and light emitting device including the same, liquid crystal display device, and illumination device

A color conversion composition that converts incident light into light having a wavelength longer than that of the incident light, the color conversion composition comprising:

• a compound represented by Formula (1):
• (R1 to R4 are the same or different from each other and selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, an aralkyl group, an alkenyl group, a cycloalkenyl group, an alkynyl group, a hydroxy group, a mercapto group, an alkoxy group, an alkylthio group, an aryl ether group, an aryl thioether group, an aryl group, a heteroaryl group, a heterocyclic group, a halogen, a haloalkane, a haloalkene, a haloalkyne, a cyano group, an aldehyde group, a carbonyl group, a carboxy group, an ester group, a carbamoyl group, an amino group, a nitro group, a silyl group, a siloxanyl group, and a ring structure formed between adjacent substituents;
• Ar1 to Ar4 are the same or different from each other and are groups represented by Formula (2):
• R5 is selected from the group consisting of an alkyl group, a cycloalkyl group, an alkoxy group, and an alkylthio group;
• m is an integer of 1 to 3;
• when m is 2 or more, each R5 is the same as or different from each other;
• with the proviso that Ar1≠Ar2 or Ar3≠Ar4 and at least one of Ar1 to Ar4 is a group in which R5 is an alkyl group having 4 or more carbon atoms;
• (here, “≠” refers to groups having different structures);
• and Ar5 is an aryl group or a heteroaryl group);
• and
• a binder resin.
