Patent
Active matrix substrate
TL;DR: In this paper, a plurality of TFTs arranged in a matrix are disposed on an insulating substrate, each including a drain electrode ( 18 b ) in which a first conductive layer ( 16 b ) and a second conductive layers ( 17 bb ) are laminated in this order; an interlayer insulating film ( 21 ) is deposited on each of the TFT surfaces, in which the contact holes ( 21 a ) reaching to the respective drain electrodes (18 b ) are formed.
