Abstract
A thin film transistor array board includes an insulator substrate, a matrix of gate electrodes formed on the insulator substrate and covered with a gate insulator film, a matrix of semiconductor islands formed on the gate insulator film positioning on the gate electrodes, source wirings connected to the source regions of the semiconductor islands, drain wirings connected in common to the drain regions of the semiconductor islands aligned in the same line in parallel with the columns of the gate electrode matrix, a second insulator film covering the whole surface including the drain wirings, the source wirings, the semiconductor islands and the pixel electrodes, the second insulator film having grooves exposing the drain wirings and auxiliary wirings formed in the grooves in contact with the drain wirings.
