ACTIVE MATRIX SUBSTRATE, LIQUID CRYSTAL DISPLAY PANEL, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR MANUFACTURING ACTIVE MATRIX SUBSTRATE

摘要

An active matrix substrate is provided with a lead wire led out from a switching element to a surrounding region; a pad portion formed in the lead wire, and positioned in surrounding region; an insulation layer formed so as to cover pad portion, including a passivation film formed of an inorganic material, and a planarization film positioned on passivation film and formed of an organic material, and having a contact hole formed so as to reach pad; and an ITO film positioned in contact hole, and formed on pad. ITO film is formed so as to be spaced from a part defined by planarization film in an inner periphery surface of contact hole.
