Abstract

A distance (d) from an edge of a first region (R) at places (D) where branch electrodes () extending, which branch off from an electrode line () of a second source/drain electrode (), start to overlap with a first region (R) to the electrode line () is 5 μm or more. This realizes a TFT including a comb-shaped source/drain structure that enables easy repair of a source-drain leakage.
