Abstract:
The present disclosure provides an organic light-emitting display device having a plurality of pixels arranged along first and second directions that intersect each other. Each of the pixels includes: a transistor; at least one insulating layer on the transistor, and a pixel contact hole extends through the insulating layer and exposes part of the transistor; a first electrode on the at least one insulating layer and connected to the transistor via the pixel contact hole; and a filling layer on the first electrode and filling the pixel contact hole. A first bank has a plurality of first openings, and each of the first openings exposes at least one of the first electrodes. A second bank has a plurality of second openings, and each of the second openings exposes a plurality of the first electrodes arranged along the second direction.
Abstract:
The present disclosure relates to an organic light emitting diode display having high aperture ratio. The present disclosure suggests an organic light emitting diode display comprising: a substrate having a plurality of pixel area arrayed in a matrix manner; an anode electrode formed within the pixel area on the substrate; a first bank having an open area exposing most of the anode electrode and defining an emission area; a second bank exposing the open area exposed by the first bank and some upper surface of the first bank; an organic light emitting layer covering the some upper surface of the first bank by the second bank and the most of anode electrode exposed by the first bank; and a cathode electrode formed over the substrate having the organic light emitting layer.
Abstract:
A display device may include a substrate including a display area and non-display area, a signal line disposed in the display area of the substrate, a test line disposed in the non-display area and connected to the signal line, and a first lower etching stopper layer disposed between the substrate and the test line. A rear surface edge of the substrate may be located further inside than an outer side edge of the first lower etching stopper layer. An end portion of the test line may include a portion that is located further outside than the rear surface edge of the substrate and does not overlap the substrate.
Abstract:
