Active matrix substrate and display device

摘要

On an active matrix substrate (5), metal electrodes (44) are provided below pixel electrodes (19). At least portions of a plurality of second thin-film transistors (second switching elements) (23b) are covered by light shielding films formed from the metal electrodes (44). The metal electrodes (light shielding films) (44) are covered by an interlayer insulating film (33) and an electrode film (CSa) of an auxiliary capacitance electrode (common electrode) (CS).
