Abstract
A wavelength conversion member having quantum dots is provided. The wavelength conversion member includes a quantum dot layer including quantum dots, and an organic film on a surface of the quantum dot layer. The quantum dot layer includes a first layer disposed on a first side of the wavelength conversion member that is closest to a light emitting device or on a light input surface side, and a second layer disposed on a second side of the wavelength conversion member that is farthest from the light emitting device or on a light output surface side. A light scattering agent is included in the first layer and the second layer. The quantum dots are not included in the first layer and are included in the second layer.
