Patent ID: 8773597

Claim:
A display device comprising: a substrate, wherein the display device is a liquid crystal display device, organic light emitting device (OLED), or reflection display device, wherein the substrate is patterned or information-recorded with an ink, wherein the ink fills a gap generated among patterned barriers formed on the substrate, wherein the ink 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 10 to 15 cP and having one or two polymerizable functional groups; and (b) a second monomer mixture, which is an acrylic monomer mixture comprising a low-viscosity monomer having a viscosity of 30 to 170 cP and a high-viscosity monomer having a viscosity of 10,000 cP or greater, wherein the second monomer mixture has a viscosity of 30 to 20,000 cP, and each of the monomer comprised in the mixture has at least three polymerizable functional groups, in the presence of 0 to 20 wt % of a solvent, wherein the ink can form a convex portion due to its surface tension controlled to 20 to 40 mN/m on a glass substrate, so as to compensate for its volumetric shrinkage, wherein the viscosity and the surface tension are measured at 25° C., and wherein the high-viscosity monomer is included in an amount of 4 to 9 wt % based on the ink.
