Abstract: A thin film transistor array substrate includes a substrate, at least one thin film transistor, a capacitor, an interlayer insulating layer, and a node connection line. The at least one thin film transistor is on the substrate. The capacitor is on the substrate and includes: a bottom electrode on the substrate; a top electrode overlapping the bottom electrode, the top electrode including an opening having a single closed curve shape; and a dielectric layer between the bottom electrode and the top electrode. The interlayer insulating layer covers the capacitor. The node connection line is on the interlayer insulating layer and electrically connects the capacitor to the at least one thin film transistor. An overlapping area of the bottom electrode and the top electrode is divided by the opening into two separate areas.

Abstract: A display device includes a pixel connected to a data line, a data pad connected to the data line, and a first test area. The first test area includes a test control line transmiting a test control signal, a test signal line transmitting a test signal, and a first switch connected to the data pad. The first switch includes a gate electrode connected to the test control line, first and second semiconductor layers overlapping the gate electrode, a source electrode connected to the first and second semiconductor layers, and a drain electrode spaced from the source electrode and connected to the first and second semiconductor layers. The source electrode and the drain electrode are connected to the test signal line and data pad, respectively. One of the first or second semiconductor layers includes an oxide semiconductor and the other of the first or second semiconductor layer includes a silicon-based semiconductor.
