THIN FILM TRANSISTOR ARRAY SUBSTRATE AND ELECTRONIC DEVICE INCLUDING THE SAME

Abstract:

A thin film transistor array substrate comprises a panel including the thin film transistor array substrate, and an electronic device including the panel that includes a conductive auxiliary layer disposed on the substrate, a gate electrode and first and second electrodes that are disposed on the conductive auxiliary layer and spaced apart from one another, a gate insulating film disposed on the gate electrode, and an active layer disposed on or over the gate insulating film and the first and second electrodes, and including a first region, a second region spaced apart from the first region, a first auxiliary region surrounding the first region, and a second auxiliary region surrounding the second region, where an electrical resistance of each of the first auxiliary region and the second auxiliary region is lower than that of the channel region and higher than that of each of the first and second regions.
