Abstract:
1. A method of manufacturing a display apparatus, comprising: forming a gate electrode and a first interconnect layer on a substrate; forming a gate insulating film and a first insulating film respectively on said gate electrode and said first interconnect layer, and thereafter forming a semiconductor layer mainly made of an oxide semiconductor on said gate insulating film and said first insulating film; forming a first protective film on said semiconductor layer, thereafter etching said semiconductor layer and said first protective film, forming a channel layer mainly made of an oxide semiconductor on which said first protective film is stacked, in a region aligned with said gate electrode, and removing said semiconductor layer and said first protective film from at least a region aligned with said first interconnect layer; forming a second protective film and a second insulating film respectively on said first protective film and said first insulating film, and thereafter etching said second protective film; and forming a pair of electrodes of a source and drain electrode assembly in contact with said channel layer, and forming a second interconnect layer in a position aligned with at least said first interconnect layer, wherein a portion of said first insulating film and a portion of said second insulating film are between at least a portion of said first interconnect layer and at least a portion of said second interconnect layer, and wherein said at least a portion of said first interconnect layer, said portion of said first insulating film, said portion of said second insulating film, and said at least a portion of said second interconnect layer are directly stacked in an interconnect region.
