A top emission type organic light emitting diode display substrate, a top emission type organic light emitting diode display device, and a method of forming a top emission type organic light emitting diode display substrate

摘要

The present application discloses a top emitting type organic light emitting diode display substrate having a plurality of sub pixel regions, each top emitting type organic light emitting diode display substrate comprising: a base substrate; A thin film transistor on the base substrate and including a drain electrode; And an organic light emitting diode on the side of the drain electrode remote from the base substrate. The organic light emitting diode includes a first electrode on a side of a drain electrode remote from a base substrate; An organic layer on the side of the first electrode remote from the drain electrode; And a second electrode on a side of the organic layer remote from the first electrode. The first electrode is a substantially transparent electrode and is electrically connected to the drain electrode. The drain electrode is a reflective electrode. The second electrode is a substantially transparent electrode.
