Abstract
Disclosed is an organic light-emitting diode display panel, which may effectively reduce or prevent spreading of the peeling of an organic light-emitting layer by using a bar-shaped reversed spacer, regardless of the direction in which the organic layer peels off. The organic light-emitting diode display panel may include a reversed spacer, which is disposed on a bank insulation layer having an opening and includes a reversed-trapezoidal cross section, the reversed spacer having a bar shape when viewed from the front side of the organic light-emitting diode display panel.
Claims11
An organic light-emitting diode display comprising:
- a plurality of first electrodes on a substrate;
- a bank insulation layer on the substrate including the first electrodes, the bank insulation layer having openings to expose the first electrodes;
- a plurality of reversed spacers on the bank insulation layer and including a reversed-trapezoidal vertical cross-section, the reversed spacers having a bar shape or a dot shape when viewed from a direction perpendicular to the substrate;
- an organic layer including a light-emitting layer on the first electrodes exposed through the openings, on the bank insulation layer, and on a top of each reversed spacer;
- and
- a second electrode on a surface of the substrate including the bank insulation layer and the organic layer.
