Abstract: An optical member includes a light guide plate, a wavelength conversion layer, and a reflective tape. The wavelength conversion layer is disposed on an upper surface of the light guide plate. The reflective tape includes a first side portion covering first side surfaces of the light guide plate and the wavelength conversion layer. The reflective tape includes a first surface and a second surface. The first surface is configured to reflect light of a first wavelength band and light of a second wavelength band different from the first wavelength band. The second surface is configured to absorb the light of the first wavelength band.
