1. A method of providing a display device, comprising:
providing a bank layer defining an opening on a substrate;
providing a color control layer in the opening;
providing a capping layer covering the bank layer and the color control layer;
after providing the capping layer, providing a color absorbing material layer on the capping layer;
patterning the color absorbing material layer on the capping layer, to provide a color absorbing pattern corresponding to the bank layer; and
providing a light emitting element substrate closer to the color absorbing pattern than each of the bank layer and the color control layer,
wherein
the capping layer includes a first area corresponding to the color absorbing pattern,
the bank layer includes a second area corresponding to the color absorbing pattern, and
the first area of the capping layer is between the color absorbing pattern and the second area of the bank layer.
