A pattern film forming method includes a step of producing a transfer
sheet in which a thin film is formed on a surface of a sheet-shaped
material and a step of pressing the thin film against a pattern film
formation surface of the substrate with a pressing member having convex
portions corresponding to the pattern film from a reverse surface of the
transfer sheet opposite to the thin film or a reverse surface of the
substrate opposite to the pattern film formation surface to transfer the
thin film to the substrate. A pattern film forming apparatus includes a
sheet supply device, a pressing device and a substrate transport device.
A high-definition pattern film having a desired pattern and a sharp edge
can be formed with high productivity.
