A thin-film transistor (TFT) array substrate including at least one TFT, the at least one TFT including a semiconductor layer including a source region and a drain region having a first doping concentration on a substrate, a channel region between the source and drain regions and having a second doping concentration, the second doping concentration being lower than the first doping concentration, and a non-doping region extending from the source and drain regions; a gate insulating layer on the semiconductor layer; a gate electrode on the gate insulating layer and at least partially overlapping the channel region; and a source electrode and a drain electrode insulated from the gate electrode and electrically connected to the source region and the drain region, respectively.

Thin-film transistor array substrate, method of manufacturing the same, and display device

A display apparatus comprises: a display panel configured to display an image; a touch panel disposed on the display panel; and a circuit board electrically connected to each of the display panel and the touch panel, the circuit board including a first surface and a second surface opposite the first surface. The circuit board includes: a first circuit portion including a first connection disposed in the first surface and electrically connected to the display panel; a second circuit portion including a second connection disposed in the second surface and electrically connected to the touch panel; and a bending portion configured to link the first circuit portion to the second circuit portion, and curving in a direction toward the first circuit portion.
