ACTIVE MATRIX SUBSTRATE

摘要

Disposed are a plurality of TFTs established in a matrix shape on an insulating substrate (10a), each including a drain electrode (18b) laminated with a first conductive layer (16b) and a second conductive layer (17bb) in that order; an interlayer insulating film (21) established on each TFT, formed with a plurality of contact holes (21a) each reaching to each drain electrode (18b); and a plurality of pixel electrodes (22a) established in a matrix shape on the interlayer insulating film (21), each connected to each drain electrode (18b) via each contact hole (21a), having an electrical-erosion property with the second conductive layer (17bb). At a side connecting to the pixel electrode (22a) of the drain electrode (18b), an upper surface of the first conductive layer (16b) is exposed from the second conductive layer (17bb); the interlayer insulating film (21) is disposed to cover the second conductive layer (17bb).
