Organic light emitting display device and electronic device

摘要

An organic electroluminescent device is provided. The organic electroluminescent device includes an array substrate having a white sub-pixel region and an organic electro-luminescent multi-layer structure is disposed on the white sub-pixel region of the array substrate. The organic electro-luminescent multi-layer structure comprises a bottom electrode. The bottom electrode has a thinner first portion and a thicker second portion for providing a wavelength shift of light in different directions.
