TFT ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

According to an embodiment of the present invention, there is disclosed a thin film transistor (TFT) array substrate comprising a sub-pixel units the sub-pixel unit comprises a thin film transistor device, a common electrode, a first pixel electrode layer and a second pixel electrode layer; one of the first pixel electrode layer and the second pixel electrode layer is connected to the common electrode, the other one is connected to a source electrode or a drain electrode of the thin film transistor, and the first and second pixel electrode layers are separated by an insulating layer; the second pixel electrode layer is located over the first pixel electrode layer; and the strip-like pixel electrodes make a tilt angle with an initial orientation of liquid crystals, and a gate line or a data line is parallel to the strip-like pixel electrodes close to itself. According to the embodiment, a phenomenon of orientation disorder of liquid crystals will not occur at an edge of pixel from influence of disordered electric fields.
