Abstract
A color transformation substrate comprises: a base portion having first and second light-blocking areas and first to third light-transmitting areas, where the light-transmitting areas are successively positioned along a first direction; first to third color filters positioned in the first to third light-transmitting areas, respectively; a light-blocking member positioned in the first light-blocking area, and including part contacting the base portion; a color pattern positioned in the second light-blocking area so as to contact the base portion; a first wavelength conversion pattern positioned on the second color filter so as to wavelength-convert light having a first color into light having a second color; and a second wavelength conversion pattern positioned on the third color filter so as to wavelength-convert light having the first color into light having a third color different from light having the second color. The color pattern and the first color filter comprise the same color material.
