Patent ID: 7342288

Claim:
A thin film transistor comprising (i) a semiconductor layer, which faces a gate electrode via a gate insulation layer, (ii) a source electrode and a drain electrode, which are electrically connected with the semiconductor layer, and (iii) a channel section between the source electrode and the drain electrode, wherein: the source electrode and the drain electrode are formed by applying a droplet of an electrode raw material, and have a branch section at branching-off parts thereof located off a forming area of the semiconductor layer, the branch section including a plurality of branch electrodes, at least part of which are in a forming area of the semiconductor layer, the branch electrodes of the source electrode and the branch electrodes of the drain electrode being alternately arrayed, and the branching-off parts are located at drop-on positions on which the droplet of the electrode raw material forming the source electrode and the drain electrode is to be dropped, and are positioned removed from the channel section, the position of the branching-off parts removed from the channel position is based on allowance of the drop-on positions.
