Abstract: The present disclosure relates to a backlight unit and a liquid crystal display device having a backlight unit. The backlight unit includes a light guide plate, a light source assembly positioned adjacent to a light-incident surface among lateral surfaces of the light guide plate, and an external tape covering the entire lateral surface of the light guide plate except the light-incident surface and parts of an upper surface and a lower surface of the light guide plate. Thus, the light efficiency of the backlight unit may be increased and the manufacturing costs reduced. Further, since the light efficiency of the backlight unit is increased, the luminance and power consumption of the liquid crystal display device can be improved.

Abstract: A display device may include a substrate on which pixels are defined, each pixel including a plurality of sub-pixels; a step formation layer disposed on the substrate; an adhesive layer disposed on the step formation layer; and a plurality of light-emitting elements respectively disposed in the plurality of sub-pixels, and disposed on the adhesive layer. The adhesive layer may include: a plurality of first portions respectively overlapping the light-emitting elements, a plurality of non-adhering areas respectively disposed adjacent to the plurality of first portions; and a second portion other than the plurality of first portions and the plurality of non-adhering areas. Accordingly, a transfer process may be simplified, and a transfer process time may be reduced. A method for manufacturing the display device is also disclosed.
