Patent ID: 8395717

Claim:
A liquid crystal display element comprising: a thin-film transistor in which one of a source electrode and a drain electrode is connected to a pixel electrode; and an auxiliary capacitance electrode which forms an auxiliary capacitance between the auxiliary capacitance electrode itself and the pixel electrode and is arranged to at least partially overlap with the thin-film transistor, wherein the thin-film transistor comprises: a semiconductor layer; an anti-etching layer which is arranged in contact with the semiconductor layer and made of an insulative material; and a gate electrode which is arranged to interpose the semiconductor layer between the gate electrode itself and the anti-etching layer, and a region in the auxiliary capacitance electrode which overlaps with the gate electrode has a length in a direction parallel to a channel length direction of the thin-film transistor which is shorter than a length of the gate electrode in this direction and longer than a length of the anti-etching layer in this direction.
