Abstract

A light conversion member includes a light conversion film, a first gas barrier, and a first base material. The light conversion film converts color of light from a specific color. The first gas barrier is located on a side of the light conversion film where the light to be converted is incident. The first gas barrier includes one or more gas barrier layers that prevent moisture and gas from entering the light conversion film. The first base material is located on an opposite side of the first gas barrier from a face on which the light conversion film is located. The first base material transmits the light and holds the light conversion film and the first gas barrier. For a light of the specific color, a light transmittance of the first base material combined with the first gas barrier is higher than a light transmittance of the first base material alone.
