The invention provides a thin film transistor array substrate and electronic equipment comprising the same. More specifically, the thin film transistor array substrate includes: a first active layer disposed on the substrate; a first gate insulating film disposed on the first active layer; a gate electrode disposed on the gate insulating film; a second gate insulating film disposed on the gate electrode; a second active layer disposed on the second gate insulating film, including a third region, a fourth region spaced apart from the third region, and a second channel region disposed between the third region and the fourth region, and overlapping the gate electrode; a first electrode disposed on the third region; and a second electrode spaced apart from the first electrode and disposed on the fourth region. As a result, it is possible to provide a thin film transistor array substrate including one or more thin film transistors having high current characteristics in a small area, and an electronic device including the thin film transistor array substrate.
Description
technical field [0001] The present disclosure relates to a thin film transistor array substrate and electronic equipment including the thin film transistor array substrate. Background technique [0002] With the advent of the information society, demands for various types of electronic devices such as display devices, lighting devices, and the like are increasing. Such an electronic device includes a panel provided with data lines and gate lines, a data driver for driving the data lines, and a gate driver for driving the gate lines. [0003] Generally, a plurality of transistors having various functions for driving are arranged in a panel which is a core element of such an electronic device. [0004] Therefore, the process of manufacturing the panel inevitably becomes complicated and difficult. Meanwhile, performance of circuit components such as transistors may deteriorate in the case of focusing on process convenience. [0005] In addition, in order to realize excellent...
