    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.

    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.

    Abstract: A display device manufacturing apparatus includes a support portion including a core portion and a conductive portion disposed over the core portion. The core portion includes a first flat surface extending in a first direction; a second flat surface extending in the first direction and being opposite to the first flat surface; and a curved surface extending between the first flat surface and the second flat surface. The conductive portion includes a first flat conductive portion overlapping the first flat surface of the core portion in a second direction; a second flat conductive portion overlapping the second flat surface of the core portion in the second direction; and a curved conductive portion extending between the first flat conductive portion and the second flat conductive portion.
