Abstract: A light source unit includes a plate including a front surface and a rear surface opposite to the front surface, a light scattering section on the front surface of the plate, a light controlling section on the light scattering section and including a plurality of quantum dots, a light source on the rear surface of the plate and including a light emitting element which generates light, a light emitting surface from which the light is emitted, and a plurality of lead frames connected to the light emitting element. The light source provides light from the rear surface of the plate toward the light controlling section. The light emitting surface of the light source is in contact with the rear surface of the plate.

Abstract: A display device includes a light emitting unit which generates and emits a first color light; an optical member in which the first color light which is incident from the light emitting unit is color-converted and from which color-converted light is emitted; and a display panel to which the color-converted light which is emitted from the optical member is provided. The optical member includes: a quantum dot member which transmits a portion of the first color light and color-converts a portion of the first color light into a second color light and a third color light; and a filter member between the light emitting unit and the quantum dot member, the filter member including a cholesteric liquid crystal layer which reflects the second color light or the third color light which is incident to the filter member from the quantum dot member.
