METHOD OF FORMING PLASTIC SUBSTRATE

摘要

A method of forming a plastic substrate is provided to improve the safety and reliability of the plastic substrate by forming a protection layer on the plastic substrate for preventing the penetration of the moisture, and oxygen. A coating layer is formed by spraying a mixture including the inorganic material on an organic substrate(10) and organic compound. A protective film(30) including the inorganic material layer(31) and organic layer(32) are formed on the organic substrate. The inorganic material layer is formed with the specific gravity difference since the inorganic material is accumulated in the surface of the organic substrate.
