LIQUID-CRYSTAL DISPLAY ELEMENT

摘要

This invention provides a liquid-crystal display element that has the following: a first substrate and a second substrate laid out so as to face each other; thin-film transistors that are provided on the first substrate and sandwich a liquid-crystal layer containing a liquid-crystal composition between the first and second substrates; and pixel electrodes that are driven by said transistors and comprise a transparent conductive material. Each thin-film transistor has a gate electrode, an oxide semiconductor layer provided such that an insulating layer is interposed between said oxide semiconductor layer and the gate electrode, and a drain electrode and a source electrode provided so as to be electrically connected to the oxide semiconductor layer. The liquid-crystal composition contains one or more compounds selected from the group consisting of compounds that can be represented by general formulas (LC3) through (LC5) and one or more compounds selected from the group consisting of compounds that can be represented by general formulas (II-a) through (II-f).
