Abstract

A thin film semiconductor substrate for a display device includes a thin film semiconductor circuit layer formed on a single crystal semiconductor substrate and a support substrate formed over the thin film semiconductor circuit layer. An adhesive layer made of a fluorine-containing epoxy family adhesive is provided between the insulating layer and the support substrate. When the single crystal semiconductor substrate is removed, the yield rate in production of the thin film semiconductor substrate is greatly improved.
