Title:
LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/061237
Kind Code:
A1
Abstract:
A coating layer (240) is formed by Atomic Layer Deposition (ALD) and includes an insulating inorganic material. An intermediate layer (220) includes a material having a linear expansion coefficient different from that of the material in the coating layer (240). A buffer layer (230) has a first surface in contact with the intermediate layer (220). The buffer layer (230) has a second surface that comes in contact with the coating layer (240). The difference between the linear expansion coefficients for the material in the buffer layer (230) and the inorganic material in the coating layer (240) is smaller than the difference between the linear expansion coefficients for the material in the intermediate layer (220) and the inorganic material in the coating layer (240).
