INK COMPOSITION FOR PHOTOCONVERSION LAYER FORMATION, PHOTOCONVERSION LAYER, AND COLOR FILTER

摘要

Phosphorus-based antioxidants such as phosphorous acid triesters were used in past inks for photoconversion layers, but hydrolysis of the antioxidant generates phosphorous acid, and phosphorous acid can impair the function of luminescent nanocrystal particles. Therefore, there has been a demand for an ink composition capable of forming a photoconversion layer having exceptional external quantum efficiency. This ink composition is an ink composition for photoconversion layer formation, the ink composition containing luminescent nanocrystal particles, a photopolymerizable compound, and a hypophosphorous acid diester compound.
