Organic light emitting display device

An organic light emitting display device comprises a substrate having a plurality of sub-pixels arranged in a first direction and a second direction intersecting the first direction; a plurality of first electrodes disposed to correspond to the plurality of sub-pixels; a first bank having a plurality of first openings exposing a portion of the plurality of first electrodes; and a second bank disposed on the first bank, having a plurality of second openings that exposes the plurality of first electrodes, and at least one third opening disposed between two neighboring second openings along the second direction.

An electroluminescent display device which may improve display quality is discussed. The electroluminescent display device includes a substrate in which a plurality of pixel areas are defined, a first electrode arranged in each pixel area, a light emitting layer on the first electrode within the pixel area, and a second electrode on the light emitting layer. Particularly, a step difference portion is arranged at an edge of the pixel area, and is partially or fully be filled with the light emitting layer. Film uniformity of the light emitting layer within the pixel area may be improved by arrangement of the step difference portion.

Electroluminescent display device

An organic light emitting display panel and an organic light emitting display device according to the present invention may include a substrate, a pixel electrode positioned in each of a plurality of pixel areas on the substrate, a bank positioned in a non-emission area on the substrate, having a portion overlapping an edge of each pixel electrode and exposing a portion of each pixel electrode, and an organic layer positioned on each exposed pixel electrode. A plurality of grooves or holes may be positioned in the bank, and a material the same as that of the organic layer may be positioned in the groove or hole.
