Abstract
An optical member includes a light guide plate, a first low refractive layer, a wavelength conversion layer, and a passivation layer. The first low refractive layer is disposed on the light guide plate. A refractive index of the first low refractive layer is smaller than a refractive index of the light guide plate. The wavelength conversion layer is disposed on the first low refractive layer. The passivation layer is disposed on the wavelength conversion layer. The passivation layer covers a side surface of the wavelength conversion layer and a side surface of the first low refractive layer on at least one side.
