LIGHT EMITTING DIODE, DISPLAY SUBSTRATE AND DISPLAY DEVICE HAVING THE SAME, AND FABRICATING METHOD THEREOF

摘要

A light emitting diode comprising a plurality of sub-pixels comprises a first electrode layer, wherein the first electrode layer is a reflective electrode layer, a second electrode layer, a light emitting layer between the first electrode layer and the second electrode layer, a first microcavity tuning layer sandwiched by the first electrode layer and the light emitting layer within the plurality of sub-pixels and a second microcavity tuning layer sandwiched by the first microcavity tuning layer and the light emitting layer within at least one of the plurality of sub-pixels. The first microcavity tuning layer is sandwiched by the first electrode layer and the second microcavity tuning layer within the at least one of the plurality of sub-pixels. The first microcavity tuning layer is made of a material including a transparent conductive material in a first state and the second microcavity tuning layer is made of a material including a transparent conductive material in a second state. The first state and the second state are different states selected from a crystalline state and an amorphous state.
