A display device is disclosed. The display device includes: a substrate including a plurality of sub-pixels; an auxiliary line disposed between the plurality of sub-pixels on the substrate; an overcoating layer including a base part having an opening that exposes the auxiliary line and a plurality of protrusion parts protruding from the base part; a first electrode corresponding to each of the plurality of sub-pixels and covering the base part and the plurality of protrusion parts; a bank on a part of the first electrode; an organic layer on the first electrode and the bank; and a second electrode on the organic layer and in contact with the auxiliary line exposed through the opening. An end portion of the bank overlaps with the opening.

Display device

A display device can include a substrate including a plurality of sub-pixels, an overcoating layer on the substrate and including a base portion and protrusion portions, a first electrode corresponding to each of the plurality of sub-pixels and covering the base portion and the protrusion portions, a bank on a portion of the first electrode, an organic layer on the first electrode and the bank, a second electrode on the organic layer, an encapsulation unit on the second electrode, and a color filter on the encapsulation unit. The color filter can overlap another portion of the first electrode that is exposed by the bank. Therefore, it is possible to improve a luminance viewing angle and lateral visibility by disposing the color filter to overlap the emission area alone.

There is provided a display device. The display device includes an optical structure disposed to increase the amount of light emitted from a light-emitting diode; and a bank coupled with the optical structure.
