Color conversion substrate and display device including the same

A display device comprising:

• an emission substrate;
• and
• a color conversion substrate disposed on the emission substrate, wherein
• the emission substrate includes:
• a lower substrate;
• and
• a first pixel electrode, a second pixel electrode, and a third pixel electrode disposed on the lower substrate,
• the color conversion substrate includes:
• an upper substrate including a first area and a second area adjacent to the first area;
• and
• a first color filter, a second color filter, and a third color filter disposed under the upper substrate and overlapping the first pixel electrode, the second electrode, and the third electrode, respectively in a plan view, and
• an opening that exposes the first color filter is defined by a one of the second color filter and the third color filter having a smaller stitch error between the first area and the second area.
