Display device and method of repairing the same

A display device comprising a pixel unit configured to emit light, the display device comprising:

• a lower substrate;
• a plurality of light-emitting devices on the lower substrate;
• an upper substrate on the lower substrate, the plurality of light-emitting devices being between the upper substrate and the lower substrate;
• a bank layer on one surface of the upper substrate facing the lower substrate, the bank layer comprising partition walls defining a central opening corresponding to the pixel unit and an auxiliary opening adjacent to the central opening;
• a color filter layer between the upper substrate and the bank layer and overlapping the central opening and the auxiliary opening, the color filter layer comprising a plurality of color filters overlapping each other in a thickness direction;
• a functional layer filling the central opening, the functional layer comprising at least one of quantum dots and scattering particles;
• and
• a low refractive index layer between the color filter layer and the functional layer,
• wherein the plurality of light-emitting devices comprises a main light-emitting device overlapping the central opening and an auxiliary light-emitting device overlapping the auxiliary opening,
• wherein the color filters of the color filter layer comprising a first color filter overlapping a first opening of the central opening, a second color filter overlapping a second opening of the central opening, and a third color filter overlapping a third opening of the central opening,
• wherein the first color filter, the second color filter, and the third color filter overlap each other in the auxiliary opening.
