    Abstract: A display device having improved reliability includes a substrate including a display area and a peripheral area outside the display area. The display area includes a central display area, a first bending display area contacting the central display area and bent about a first bending axis, and a second bending display area bent about a second bending axis intersecting the first bending axis. The peripheral area includes a corner area rounded and adjacent to the first bending display area and the second bending display area. This display device includes an inorganic layer disposed at the display area and the peripheral area, an opening pattern formed in the inorganic layer and corresponding to the corner area, and a first organic material layer covering the opening pattern.

    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.
