Photoluminescent panel, photoluminescent liquid crystal display device, and method of manufacturing the photoluminescent panel

A photoluminescent liquid crystal display device comprising:

• a backlight unit which emits light having a desired wavelength;
• a first substrate on the backlight unit;
• a second substrate facing the first substrate and comprising a plurality of color areas spaced apart from each other by a gap therebetween;
• a liquid crystal layer between the first and the second substrates;
• and
• a color conversion layer on the second substrate, and comprising
• a reflection wall provided in plural to define pairs of adjacent reflection walls among which first pairs of adjacent reflection walls define the color areas therebetween;
• and
• a flattening layer commonly disposed between each pair of adjacent reflection walls, the flattening layer comprising a base material layer in which a light excitation particle which absorbs light having a desired wavelength and emits excited light, and a scattering particle which scatters the excited light are distributed,
• wherein a same base material layer including a portion of the base material layer in which the light excitation particle is disposed extends from between the first pairs of adjacent reflection walls to be disposed at the gap between color areas.
