1. A method for manufacturing a display device, the method comprising:
forming a first color filter transmitting a first color light on a base substrate to overlap a plurality of first light-emitting areas;
forming a second color filter transmitting a second color light different from the first color light, the second color filter overlapping a plurality of second light-emitting areas and a first portion of a light-blocking area, the first portion of the light-blocking area disposed between two of the first light-emitting areas adjacent to each other;
forming a partition wall including a first opening, the first opening continuously overlapping the two of the first light-emitting areas, which are adjacent to each other, and the first portion of the light-blocking area, which is disposed between the two of the first light-emitting areas so that the first opening further overlaps a portion of the second color filter on the first portion of the light-blocking area;
providing a first composition including a wavelength-converting material in the first opening; and
curing the first composition to form a first color-converting layer that is continuous across the two of the first light-emitting areas.
