Abstract

A blue photoresist composition capable of emitting infrared light, a method of preparing the blue photoresist composition capable of emitting infrared light, a color filter including blue sub-pixels formed from the blue photoresist composition capable of emitting infrared light, and a display device including the color filter. The blue photoresist composition capable of emitting infrared light includes, based on the total weight of the composition, 2% to 20% of a color mixed material, 30% to 90% of a solvent, 2% to 25% of an alkali-soluble resin, 2% to 20% of an unsaturated monomer, 0.01% to 1% of photoinitiator, and 0.005% to 0.02% of other additives; wherein the color mixed material includes a colorant and a surface-modified infrared light-emitting material at a weight ratio of 20:1 to 1:1.
