A
display device including a first substrate, a pixel unit disposed on the first substrate and including a first sub-pixel
electrode, a second sub-pixel
electrode and a third sub-pixel
electrode, the first through third sub-pixel electrodes being adjacent to one another, a second substrate facing the first substrate, a first
wavelength conversion layer disposed on a surface of the second substrate facing the first substrate, and overlapping the first sub-pixel electrode, a second
wavelength conversion layer disposed on the surface of the second substrate facing the first substrate, and overlapping the second sub-pixel electrode, a transmissive layer disposed on the surface of the second substrate facing the first substrate, and overlapping the third sub-pixel electrode, a first
cholesteric liquid crystal layer disposed on a surface of the first
wavelength conversion layer facing the first substrate, a second
cholesteric liquid crystal layer disposed on a surface of the second
wavelength conversion layer facing the first substrate, and a planarization layer disposed on the surfaces of the first and second
cholesteric liquid crystal layers facing the first substrate and on a surface of the transmissive layer facing the first substrate. Methods of manufacturing a
display device capable of reducing the number of process steps in the manufacturing process are also disclosed.
