Abstract: Provided are a light source assembly and a backlight assembly including a lens module. The light source assembly includes: a light source module capable of emitting light and a lens module positioned on the light source module. The lens module includes a light collecting lens collecting the light emitted from the light source module, and a diffusion lens positioned on the light collecting lens, and including an inner curved surface in which light from the light collecting lens is incident and an outer curved surface where the light incident on the inner curved surface exits the diffusion lens, and the light emitted from the light source module forms a light collecting region on the inner curved surface by passing through the light collecting lens.

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.
