A liquid crystal display element includes a thin-film transistor in which one of source and drain electrodes is connected to a pixel electrode, and an auxiliary capacitance electrode that forms an auxiliary capacitance together with the pixel electrode and at least partially overlaps with the thin-film transistor. The thin-film transistor includes a semiconductor layer, an anti-etching layer that is arranged in contact with the semiconductor layer and made of an insulative material, and a gate electrode that is arranged to interpose the semiconductor layer between the gate electrode itself and the anti-etching layer. A region in the auxiliary capacitance electrode that overlaps with the gate electrode has a length in a direction parallel to a channel length direction of the thin-film transistor that 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.
