A backlight unit includes a light source unit having a light source configured to emit a first light, a quantum dot sheet configured to emit a second light having a different color from the first light, a light guide plate configured to guide a light exiting from the light source unit or the quantum dot sheet, and an optical member including a prism sheet and configured to control the light exiting from the light guide plate. The quantum dot sheet includes a polymer resin and a plurality of first and second quantum dots, which are dispersed in the polymer resin. The second light is a white light obtained by mixing a red light, green light, and a blue light, and the second light has a concordance rate with an Adobe RGB color space which is no less than by about 99.9%.

Backlight unit and display apparatus having the same

A backlight unit includes a light source which generates a first light; a quantum dots member which is spaced apart from the light source by a first distance and converts the first light into a second light; a guide member which lengthwise extends in a first direction and fixes positions of the light source and the quantum dots member; and an optical member which reflects the second light. The guide member guides the first light from the light source to the quantum dots member and guides the second light from the quantum dots member to the optical member.

Backlight unit and display device including the same

A display apparatus includes a light source part, a light guide plate, and a display panel. The light source part includes first light sources and second light sources alternately arranged to emit a light having a color different from a color of a light emitted from the second light sources. The light guide plate includes an incident surface having at least one light incident surface facing the light source to guide the light. The display panel receives the light from the light guide plate to display an image. A distance between end portions of the incident surface and the first and second light sources disposed and corresponding to each end portion of the light incident surface is different from a distance between a center portion of the light incident surface and the first and second light sources disposed and corresponding to the center portion.
