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.

Abstract: An optical member including a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.
