摘要: A backlight unit includes a first substrate, a plurality of LED chips on one surface of the first substrate and configured to emit light of a first color, a second substrate located opposite to the one surface of the first substrate, and a plurality of light modulation patterns on one surface of the second substrate facing the one surface of the first substrate so as to overlap the plurality of LED chips, respectively. Each of the plurality of light modulation patterns includes a first wavelength conversion pattern that converts the light of the first color into light of a second color. The first wavelength conversion pattern includes a first wavelength conversion layer on the one surface of the second substrate, a first organic encapsulation layer on the first wavelength conversion layer, and a barrier structure covering the first wavelength conversion layer and the first organic encapsulation layer.
