Abstract:
A light conversion plate including a first glass substrate; a light conversion layer disposed on the first glass substrate and including quantum dots that convert incident light into light having a specific wavelength range; and a second glass substrate disposed on the light conversion layer. Further, a surface of at least one of the first glass substrate and the second glass substrate includes a plurality of protrusion patterns.
