ORGANIC LIGHT EMITTING DIODE, ARRAY SUBSTRATE AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE

摘要

An organic light emitting diode, an array substrate and a preparation method therefor, and a display device. The organic light emitting diode comprises: a first electrode, an organic light emitting layer (113) and a second electrode (114), the first electrode comprising an optical resonance layer structure for enabling light generated by the organic light emitting layer (113) to generate resonance. The light utilization rate of the organic light emitting layer (113) can be improved via the optical resonance layer structure.
