• a colorant;
• a photopolymerizable compound;
• a photopolymerization initiator;
• a binder resin;
• and
• a solvent,
• wherein:
• the colorant includes a pigment, a dispersant, and a dispersing aid represented by Chemical Formula 1,
• in Chemical Formula 1,
• M is Cu or Zn;
• R11 to R14, R21 to R24, and R31 to R34 are each independently a hydrogen atom, a halogen atom, a hydroxy group, or a substituted or unsubstituted C1 to C20 alkyl group;
• and
• R41 to R44 are each independently a hydrogen atom, a halogen atom, a hydroxy group, a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C1 to C20 alkoxy group, provided that at least one of R41 to R44 is a C1 to C20 alkoxy group substituted with a sulfonate group.
