Abstract
A photoresist composition for manufacturing a color filter, the photoresist composition includes a first red colorant and a yellow colorant represented by Chemical Formula 1, wherein R1 and R2 each independently represent a C1 to C10 alkyl group, wherein A1, A2, A3, and A4 each independently represent a C1 to C10 alkyl group, —CN, —PO3H2, —C(O)OH, or a hydrogen atom, m is an integer of 1 to 10, and optionally wherein at least one —CH2— of R1 and R2 if present is independently replaced with —O—, —C(O)—, —C(O)O—, or —OC(O)—.
