Thin film transistor array substrate and liquid crystal display device

摘要

The present invention provides a thin film transistor array substrate and a liquid crystal display device including the thin film transistor array substrate that are preferably applicable to a liquid crystal display device including the three-layered electrode structure that enables high response speed and high transmittance, and can have a high aperture ratio. The thin film transistor array substrate of the present invention includes: a thin film transistor element, gate bus lines, and source bus lines, in which the thin film transistor array substrate includes electrodes, the electrodes include a first electrode and a second electrode, the first electrode includes a linear portion along the source bus lines, the first electrode includes a linear portion along the gate bus lines, at least one linear portion along the source bus lines is disposed transversely to the linear portion along the gate bus lines in a plan view of main face of the substrate and is connected to a drain electrode of the thin film transistor element at a position overlapping the gate bus lines, and the second electrode is a planar electrode.
