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.
