Abstract
A fabricating method of a device substrate including the following procedures is provided. First, a substrate is provided and a patterned structure is formed on the substrate, wherein the patterned structure includes a plurality of openings. Then, a protective layer is formed on the patterned structure, wherein the protective layer does not fully fill the openings of the patterned structure such that a gap is existed between the protective layer and the patterned structure. Later, a device layer is formed on the protective layer.
