Abstract
A photoluminescent panel includes a lower substrate, an upper substrate facing the lower substrate, a liquid crystal layer disposed between the lower substrate and the upper substrate, and a color conversion layer disposed on the upper substrate. The color conversion layer includes a light excitation particle which absorbs light having a desired wavelength and emits excited light, and a scattering particle which scatters the excited light.
Claims15
A photoluminescent panel comprising:
- a lower substrate;
- an upper substrate facing the lower substrate and comprising a plurality of color areas spaced apart from each other by a gap therebetween;
- and
- a color conversion layer on the upper 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.
