Abstract

A thin film transistor array substrate including a substrate, a plurality of scan lines disposed on the substrate, a plurality of data lines disposed on the substrate, a first pixel rows disposed on the substrate and a second pixel group disposed on the substrate is provided. The first pixel group has a first reflective region and a first transmissive region. The second pixel group has a second transmissive region and a second reflective region, the first pixel group and the second pixel group are controlled by the scan lines and the data lines and arranged alternatively along a column direction, wherein the first transmissive region is contiguous to the second transmissive region.
