摘要： 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.

摘要： A display device includes a defect inspection circuit, and a display panel having a display area and a peripheral area positioned outside the display area. The display panel includes a sensing wire positioned in the peripheral area and connected to the defect inspection circuit. The defect inspection circuit includes a resistance detection circuit that detects a resistance of the sensing wire based on an output signal corresponding to the sensing wire, a memory that stores first resistance information related to the resistance of the sensing wire detected in a first inspection operation, and a comparator circuit including a first comparator that compares the first resistance information with second resistance information. The second resistance information is related to the resistance of the sensing wire detected in a second inspection operation that is performed at a different time than the first inspection operation.
