SUBSTRATE FOR PHOTOELECTRIC DEVICE AND PHOTOELECTRIC DEVICE COMPRISING SAME

摘要

An optoelectronic device substrate can ensure that constituent thin films of an optoelectronic device be flat and that a functional thin film formed to improve the characteristics of the optoelectronic device be structurally stable so that the functional thin film maintains its function. An optoelectronic device including the same is provided. The optoelectronic device substrate includes a base substrate and a patterned structure formed on the base substrate. A planarization layer is disposed on the patterned structure, the planarization layer being formed from a two-dimensional material.
