Abstract
A thin film transistor (TFT) array substrate has a plurality of pixel units. A plurality of signal lines and a plurality of scanning lines are formed on the substrate. Each of the plurality of paired and adjacent signal lines and each of the plurality of scanning lines are arranged in a matrix form to define each pixel unit. Each pixel unit includes at least two pixels, which are abreast of the paired and adjacent signal lines. This structure thereby provides a TFT array substrate with high aperture ratio pixel structure.
