The background member includes a first white resin layer and a second white resin layer on the first white resin layer, and an invisible light absorption layer on the second white resin layer. The second white resin layer has a visible light resistance higher than the first resin layer. The invisible light absorption layer absorbable the invisible light. The invisible light absorption layer, the second white resin layer, and the first white resin layer are disposed in this order in the light incident direction.
