    Abstract: An optical member and a display device including the same. The optical member includes 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.

    Abstract: An optical member includes a light guide plate in which light incident thereto is propagated, including: an emission surface through which propagated light exits the light guide plate, a light incident side surface through which the light is incident to the light guide plate, and an inclined edge surface connecting the emission and light incident side surfaces to each other; and a wavelength conversion layer to which exited light from the light guide plate is incident and which converts a wavelength of the exited light, disposed facing the emission surface of the light guide plate. The inclined edge surface and emission surfaces define a boundary therebetween, and a side surface of the wavelength conversion layer which is closest to the light incident side surface is further from the light incident side surface than the boundary between the inclined edge surface and the emission surface.
