본 발명의 일 양태인 색변환 부재는, 입사광을, 그 입사광과는 다른 파장의 광으로 변환하는 색변환 부재이며, 적어도 이하의 (A)층 및 (B)층을 포함한다. 상기 (A)층은, 적어도 1종의, 지연 형광을 방출하는 유기 발광 재료와, 결합제 수지를 함유하는 색변환층이다. 상기 (B)층은, 산소 투과도가 1.0cc/㎡·day·atm 이하의 층이다. A color conversion member in an aspect of the present invention is a color conversion member that converts incident light into light of a wavelength different from the wavelength of the incident light, and includes at least the following (A) layer and (B) layer. The (A) layer is a color conversion layer containing: at least one organic luminescent material that emits delayed fluorescence; and a binder resin. The (B) layer is a layer having an oxygen permeability of 1.0 cc/m2·day·atm or less.
