Abstract

The present invention relates to a composition for forming a quantum dot layer comprising: at least one active energy ray-curable compound (A) having an ethylenically unsaturated double bond, at least one thiol compound (B) having at least two mercapto groups in one molecule, a photo-initiator (C); quantum particles (D), and scattering particles (E), wherein the composition contains 0.20-0.80 equivalents of the compound (B) per one equivalent of the compound (A), and the W value of the compound (A) calculated by Math formula 1 is 3.0 or more, and the present invention also relates to a quantum dot film, a backlight unit, and a liquid crystal display.
