Abstract: A display device includes a display area configured to include a plurality of pixels and a plurality of data lines connected to the pixels. A hole area is disposed within the display area. A hole crack detection line is disposed adjacent to the hole area and surrounds the hole area. The device includes first and second detection lines which include first and second detection transfer lines and first and second detection receiving lines, respectively. A test controller electrically connects the first detection receiving line to a first data line and the second detection receiving line to a second data line. Pixels connected to the first data line that is connected to a first bright-line transistor and pixels connected to the second data line that is connected to a second bright-line transistor are configured to emit light when a crack occurs in the hole crack detection line.

Abstract: A pixel includes a main circuit, a sub circuit, and an organic light emitting diode. Each of the main circuit and the sub circuit includes a switching transistor to switchably operate based on a first scan signal, a driving transistor to receive a data voltage through the switching transistor, and a storage capacitor to store the data voltage. The organic light emitting diode emits light based on current flowing through one of the main circuit or the sub circuit.
