Positive Type Photosensitive Siloxane Composition, Active Matrix Substrate, Display Apparatus, and Method of Manufacturing Active Matrix Substrate

摘要

The present invention provides a positive type photosensitive siloxane composition in which a film formed by the same has high heat resistance, high strength and high crack resistance, an active matrix substrate in which by-product is not generated, an occurrence of defects is suppressed, and an interlayer insulating film is easily formed at a low cost while having good transmittance, a display apparatus including the active matrix substrate, and a method of manufacturing the active matrix substrate. An active matrix substrate includes a plurality of gate wirings provided so as to extend parallel to each other on an insulating substrate, and a plurality of source wirings provided so as to extend parallel to each other in a direction intersecting the respective gate wirings. An interlayer insulating film and a gate insulating film are interposed at portions including the intersecting portions of the gate wirings and the source wirings, on a lower side of the source wiring. The interlayer insulating film is formed using the positive type photosensitive siloxane composition without using a resist.
