Thin film transistor substrate and display device

摘要

The present invention provides a thin film transistor substrate and a display device that prevent peeling. The thin film transistor substrate includes: an insulating substrate; a thin film transistor; a first inorganic insulating layer; an organic insulating layer stacked on the first inorganic insulating layer; and a second inorganic insulating layer stacked on the organic insulating layer. The organic insulating layer includes a side covered with the second inorganic insulating layer. The first inorganic insulating layer may contain silicon oxide. The organic insulating layer may contain photosensitive resin. The second inorganic insulating layer may contain silicon nitride.
