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.
