<p>A pigment dispersion composition is provided to realize excellent pigment dispersibility and dispersion stability, to form a coating layer cured by light exposure and to ensure excellent light transmission and contrast. A pigment dispersion composition comprises: a pigment and a polymer having copolymerized units derived from a monomer represented by the following formula 1, in an organic solvent. In formula 1, R1 is H or a substituted or non-substituted alkyl; R2 is alkylene; W is -CO-, -C(=O)O-, -CONH-, -OC(=O)- or phenylene; X is -O-, -S-, -C(=O)O-, -CONH-, -C(=O)S-, -NHCONH-, -NHC(=O)O-, -NHC(=O)S-, -OC(=O)-, -OCONH- or -NHCO-; Y is -NR3-, -O-,-S- or -N=, and is linked to N by way of an atomic group adjacent thereto to form a cyclic structure; R3 is H, alkyl or aryl; and each of m and n represents 0 or 1.</p> |
