    Abstract: A display device can include a first light emitting area, a second light emitting area positioned outside the first light emitting area and positioned to be spaced apart from the first light emitting area, a third light emitting area positioned outside the second light emitting area and continuously positioned in contact with the second light emitting area, a second non-light emitting area positioned between the first light emitting area and the second light emitting area, and a first non-light emitting area positioned outside the third light emitting area. As a result, the display device is capable of maximally suppressing a change in color coordinates even at a wide viewing angle.

    Abstract: A subpixel for a display device can include a transistor disposed on a substrate; a first planarization layer disposed on the transistor, the first planarization layer including a concave portion that corresponds to an emission area of the subpixel; an anode electrode disposed in the concave portion of the first planarization layer, a light emitting layer disposed on the anode electrode; and a bank disposed on the anode electrode. Also, a portion of the bank is disposed in the concave portion of the first planarization layer in an area between a portion of light emitting layer and a portion of an inclined side surface of the anode electrode.

    Abstract: 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.

    Abstract: 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.
