Abstract
A thin film transistor (TFT) array substrate comprising a sub-pixel unit is disclosed. The sub-pixel unit includes a thin film transistor device, a first pixel electrode layer and a second pixel electrode layer; the first pixel electrode layer is configured as a common electrode, the second pixel electrode layer is connected to a source electrode or a drain electrode of the thin film transistor, and the first pixel electrode layer is insulated from the second pixel electrode layer; the second pixel electrode layer is located over the first pixel electrode layer, and strip-like pixel electrodes of the second pixel electrode layer overlap the first pixel electrode layer; and strip-like pixel electrodes of the second pixel electrode layer which are extended along a straight line make a tilt angle with an initial alignment of liquid crystals, and a data line is parallel to one of the strip-like pixel electrodes close to the data line. A phenomenon of orientation disorder of liquid crystals will not occur at an edge of pixel from influence of disordered electric fields.
