Precursor composition for thin film deposition, method for manufacturing thin film and thin film manufactured using the same, and electronic device comprising thin film

A manufacturing method of a thin film, comprising:

• preparing a precursor composition for deposition of the thin film by mixing liquid indium precursor, liquid gallium precursor, and liquid zinc precursor;
• and
• forming the thin film on a substrate by using the precursor composition.

An electronic device comprising:

• a thin film formed by using a precursor composition comprising liquid indium precursor, liquid gallium precursor, and liquid zinc precursor,
• wherein the thin film is a single amorphous layer including indium, gallium and zinc.
