Abstract
A thin film transistor array substrate includes pixel regions, each comprising first, second and third transparent electrodes, which are electrically isolated, wherein the second transparent electrode comprises strip-like second electrode portions electrically connected to one another, and the third transparent electrode comprises strip-like third electrode portions electrically connected to one another, the positions of the strip-like third electrode portions corresponding to those of the strip-like second electrode portions, and wherein the strip-like third electrode portions have a width less than that of the strip-like second electrode portions. When the substrate is actuated, a first horizontal electric field is formed between the first and second transparent electrodes and a second horizontal electric field is formed between the third and second transparent electrodes, so that the transmittance can be increased.
