COLOR CONVERSION SHEET, LIGHT SOURCE UNIT COMPRISING SAME, DISPLAY AND LIGHTING DEVICE

A color conversion sheet according to a mode of the present invention is a color conversion sheet that converts incident light into light with a wavelength longer than that of the incident light and includes the following layer (A) and layer (B). This color conversion sheet is used for a light source unit, a display, and a lighting apparatus. The layer (A): a layer containing an organic light-emitting material (a) that exhibits light emission with a peak wavelength observed in a region of 500 nm or more and 580 nm or less by using excitation light in a wavelength range of 400 nm or more and 500 nm or less and a binder resin; and the layer (B): a layer containing an organic light-emitting material (b) that exhibits light emission with a peak wavelength observed in a region of 580 nm or more and 750 nm or less by being excited by either or both of excitation light in a wavelength range of 400 nm or more and 500 nm or less and light emission from the organic light-emitting material (a) and a binder resin.
