Disclosed is an ink, which has a viscosity and a volumetric shrinkage, controlled to 20~80 cP and 10~30%, respectively, by controlling an amount of each of: (a) a first monomer having a viscosity of 7~1,600 cP and having one or two polymerizable functional groups; and (b) a second monomer having a viscosity of 30~20,000 cP and having at least three polymerizable functional groups, in the presence of 0~20 wt % of a solvent, and which can form a convex portion due to its surface tension controlled to 20~40 mN/m, so as to compensate for its volumetric shrinkage, wherein the viscosity and the surface tension are measured at 25° C. A substrate, which is patterned or information-recorded with the ink, and a display device having the substrate are also disclosed.
