Abstract
A display panel and a display device are disclosed in the present application. The display panel includes a driving chip set, a pad set, and a cell test circuit, which can determine a binding state between each pin and a corresponding pad according to timing and states of binding detection signals output in correspondence with a first binding detection line and a second binding detection line, improving detection accuracy of the binding state; compared with relying on a microscope to check the binding state of each pin one by one, detection efficiency of the binding state is improved.
