Abstract
A display panel and a display device. The display panel includes a test circuit located in a non-display region. The test circuit includes a plurality of switching transistors and at least one data switching line extending in a first direction. In each switching transistor, a first end of the switching transistor is electrically connected to a data line in the display panel, and a second end of the switching transistor is configured to receive a test data signal. The data switching line is disposed in the same layer as a source-drain layer of the switching transistor. The data switching line is configured to control the switching transistor to be turned on or off.
