Abstract
Official abstract text for this publication.
A black photoresist composition capable of emitting infrared light, a method of preparing the black photoresist composition capable of emitting infrared light, a color filter comprising a Black Matrix formed from the black photoresist composition capable of emitting infrared light, and a display device including the color filter. The black photoresist composition capable of emitting infrared light includes, based on the total weight of the composition, 2% to 15% of a color mixed material, 30% to 90% of a solvent, 2% to 20% of an alkali-soluble resin, 2% to 20% of an ethenoid 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 19:1 to 1:1.
