PROBLEM TO BE SOLVED: To provide a quantum dot laminate of good front luminance.SOLUTION: A quantum dot laminate is for a back light containing a prism sheet on a quantum dot sheet, in which, the quantum dot sheet contains a quantum dot-containing layer that contains a quantum dot which absorbs primary light and emits secondary light as well as a binder resin, and when intensity of transmission light is measured for each one degree within a range of -85° to +85° while visible light whose light source is a halogen lamp (12 V, 48 W) is vertically radiated on any one surface of the quantum dot sheet, the following condition (1) is met. condition(1) (P+P)/Pis 0.65 or below where the total sum in intensity from -5° to +5° is P, total sum in intensity from -70° to -85° and +70° to +85° is P, and total sum in intensity from -15° to -45° and +15° to +45° is P.SELECTED DRAWING: Figure 1
