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.

An optical member and display device, the optical member including a diffuser plate, a wavelength conversion layer disposed on a top surface of the diffuser plate, a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer on at least one side thereof, and a diffusing pattern layer disposed on and in direct contact with a bottom surface of the diffuser plate and containing diffusion particles.

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.

A light guide panel, back light assembly and display apparatus are provided. According to an aspect of the inventive concept, there is provided the light guide panel which includes a top surface, a bottom surface, and four side surfaces, and one of the four side surfaces may be a light incident surface.

Light guide panel, back light assembly and display apparatus each having the light guide panel and method of manufacturing the light guide panel

Disclosed is a light guide plate including a base sheet and a first light transmissive adhesive layer disposed on a surface of the base sheet. The first light transmissive adhesive layer together with the base sheet define a light entrance portion. The thickness of the first light transmissive adhesive layer becomes gradually smaller from the light entrance portion toward a center portion of the base sheet. A backlight assembly includes the light guide plate.
