1. A display device comprising:
a substrate including:
a light emitting region; and
a non-light-emitting region adjacent to the light emitting region;
a storage capacitor formed in the non-light-emitting region on the substrate and having an upper electrode and a lower electrode;
a light absorption layer formed on the storage capacitor;
an anode electrode formed on the light absorption layer;
a first via hole formed in such a manner as to pass through the light absorption layer; and
a bank layer formed on the light absorption covering a top of the storage capacitor,
an overcoat layer formed of an organic material and formed between the light absorption layer and the bank layer and in the first via hole;
wherein the bank layer is not formed in the light emitting region, and
wherein the anode electrode is in direct contact with the upper electrode of the storage capacitor through the first via hole and the overcoat layer, and
wherein the light absorption layer includes a colorant capable of selectively transmitting incident light in substantially only one portion of a wavelength band by transmitting light in a first wavelength band and blocking light in a second wavelength band,
wherein the light absorption layer has a structure of at least a first absorption layer contains a pigment of a first color and a second absorption layer contains a pigment of a second color different from the first color stacked on top of each other.
