A display apparatus according to an embodiment of the inventive concept may include a display panel, a light guide panel, and the light source. The light guide plate may include a light guide portion, a barrier rib portion, a wavelength conversion portion, and a cover portion. The barrier rib portion may be disposed on an upper surface of the light guide portion. The wavelength conversion portion may be disposed on the upper surface of the light guide portion to be surrounded by the barrier rib portion. The cover portion may be disposed on the wavelength conversion portion and the barrier rib portion, and cover the wavelength conversion portion.

Display apparatus and method of manufacturing the same

A display device includes an organic fluorescent body unit and a display panel provided on the organic fluorescent body unit. The organic fluorescent body unit may include a light source unit including a light source substrate and a plurality of light sources on the light source substrate, a red organic fluorescent body layer covering the light sources and including a red organic fluorescent body, and a green organic fluorescent body layer provided on the red organic fluorescent body layer and including a green organic fluorescent body. The red organic fluorescent body layer may include a plurality of red organic fluorescent body patterns, each of which respectively covers one of the light sources.

Display device and method for manufacturing the same

A light generating member includes a light source which generates a first light, a light conversion member which converts the first light into a second light, a bottom portion which includes long sides facing each other and short sides which are connected to ends of the long sides and face each other, first sidewall portions which are connected to the long sides, extend in a direction crossing a plane of the bottom portion and face each other, and second sidewall portions which are connected to the first sidewall portions and face each other, where the light source is disposed between the bottom portion and the first sidewall portions, the light conversion member is disposed between the second sidewall portions, and the long sides have a predetermined curvature.

Light generating member, display apparatus including the same, and manufacturing method thereof

A light source unit includes a light source configured to emit a light, a first case including a first groove configured to receive the light source therein, a first sealing member disposed in the first groove and covering the light source, a second case disposed on the first case and including a first opening portion overlapping with the first groove, and a quantum dot member disposed between the first case and the second case and including a light conversion area configured to convert the light to a white light and a defect area surrounding the light conversion area. The first opening portion is disposed through the second case, a portion of the light conversion area overlaps with the first opening portion and the first groove, and the light source unit is configured such that the white light exits therefrom through the first opening portion.

Light source unit, method of manufacturing the same, and backlight unit having the same

A light generation member includes a light source which includes light source units which generate a first light, a light conversion member which converts the first light to a second light, and a light diffusion member which is elongated in a first direction, in which is defined first grooves respectively corresponding to the light source units, the light diffusion member diffusing the first light generated by the light source unites and providing the diffused first light to the light conversion member. The light diffusion member is between the light conversion member and the light source in a second direction crossing the first direction, and the first grooves defined in the light diffusion member are each elongated in a third direction substantially perpendicular to the first and second directions.

Light generation member including light diffusion member and display apparatus having the same

A light source includes a substrate and a plurality of light emitting devices disposed on the substrate. Each of the light emitting devices is configured to generate a first light. A plurality of quantum-dot devices are respectively disposed on the light emitting devices. The quantum-dot devices are configured to convert the first light to a second light. The quantum-dot devices are configured to be attached to and detached from the light emitting devices, respectively.
