A color conversion composition that is one aspect of the present invention contains component (A) and component (B) and converts incident light into light having a longer wavelength than the incidentlight. This color conversion composition and a color conversion sheet containing same can be used in a light source unit, a display, a lighting system, a backlight unit, an LED chip and an LED package. Component (A) is an organic luminescent material. Component (B) is at least one of a polyester resin having a partial structure represented by general formula (1) in the molecular structure, and a resin having a bisphenol structure represented by general formula (2). (Y is a divalent saturated aliphatic hydrocarbon group having at least 1 tertiary or quaternary carbon atom.) (R1 and R2 each denote a hydrogen atom or an organic group having 1-20 carbon atoms. R1 and R2 may be the same as, or different from, each other.) 本发明的实施方式的颜色转换组合物是含有以下的(A)成分及(B)成分、将入射光转换为波长比该入射光更长的光的颜色转换组合物。该颜色转换组合物及包含其的颜色转换片可用于光源单元、显示器、照明装置、背光
