THIN FILM TRANSISTOR ARRAY PANEL AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A thin film transistor display panel and a manufacturing method thereof are provided to form an insulating film which covers a semiconductor layer without an additional mask even though an etching stop film is not formed on the semiconductor layer. CONSTITUTION: A gate electrode(124) is arranged on an insulating substrate. A gate insulating film(140) is arranged on the gate electrode. An oxide semiconductor is arranged on the gate insulating film. Blocking layers(163,164,165) are arranged on the oxide semiconductor. A source electrode and a drain electrode are arranged on the blocking layers. A protective film(180) is arranged on the source electrode and the drain electrode. A pixel electrode is arranged on the protective film.
