The present invention relates to a light-conversion ink composition comprising light-emitting particles, polymerizable monomers, and additives represented by a specific chemical formula, to a light-conversion laminated substrate manufactured using the light-conversion ink composition, to a backlight unit comprising the same, to a light-conversion pixel substrate manufactured using the light-conversion ink composition, and to an image display device comprising the backlight unit or the light-conversion pixel substrate. According to the light-conversion ink composition, the light-conversion properties are improved compared to conventional light-conversion ink compositions. 본 발명은, 발광입자, 중합성 모노머, 및 특정 화학식으로 표시되는 첨가제를 포함하는 광변환 잉크 조성물, 상기 광변환 잉크 조성물을 이용하여 제조된 광변환 적층기판 및 이를 포함하는 백라이트 유닛, 상기 광변환 잉크 조성물을 이용하여 제조된 광변환 화소기판, 및 상기 백라이트 유닛 또는 광변환 화소기판을 포함하는 화상표시장치에 관한 것이다.
