Abstract: A color conversion substrate includes a base on which first to third light outputting regions and a light shielding region surrounding the first to third light outputting regions are defined; first to third color filters on the base in the first to third light outputting regions, respectively; a first light shielding member on the first color filter in the light shielding region; a light transmission pattern on the first color filter; a first wavelength conversion pattern on the second color filter and which converts light of a first color into light of a second color; and a second wavelength conversion pattern on the third color filter and which converts the light of the first color into light of a third color. A first opening located in the light shielding region is defined in at least one of the light transmission pattern and the first and second wavelength conversion patterns.

Abstract: An exemplary embodiment provides a display device including: a display part configured to include a display part color filter; and a peripheral part disposed at the upper side of the display part and including an inspection pattern for checking an alignment of the display part color filter. The inspection pattern may include a plurality of color filters having colors and reference patterns disposed at at least one side of the plurality of color filters. A number of the plurality of color filters of each color corresponds to a number of shots of a division exposure process. Adjacent color filters among the plurality of color filters may be disposed at different heights.

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.
