Zusammenfassung:	PURPOSE:To lower the resistance of a gate bus wiring and to improve an image grade by bringing a light shielding film into contact with the gate bus wiring of a transistor, thereby making double wirings. CONSTITUTION:The light shielding film 8 which shields the projection of incident light to allow transmission of a liquid crystal to a semiconductor thin film 5 is formed in said film; in addition, the light shielding film 8 is brought into contact with the gate bus wiring 7. Since the light shielding film 8 shields the irradiation of the incident light to the semiconductor thin film 5 and, therefore, the decrease of the off resistance of the thin-film transistor (TFT) which has the thin film 5 as a part of the constitution is prevented. Since the gate bus wiring 7 is double-wired, the resistance of the gate bus wiring is lowered. The large-sized active matrix display device having the high image grade is thereby obtd.
