Abstract: A display device can include a display panel including a light emitting element, a driving transistor for providing a driving current, and a plurality of switching transistors for controlling an operation of the driving transistor; a gate driving circuit configured to supply signals to the display panel; a data driving circuit configured to supply a plurality of data voltages to the display panel; and a timing controller. Also, the plurality of switching transistors can include a first switching transistor having a dual gate structure and configured to connect a gate node of the driving transistor with a drain node of the driving transistor in response to a first scan signal, and a stabilization transistor configured to connect the gate node of the driving transistor with a common node of the first switching transistor in response to a stabilization scan signal.

Abstract: A display device includes a display panel having a display area and a non-display area, crack lines disposed in the non-display area; and a first crack pad and a second crack pad connected to both ends of the crack lines. The crack lines comprise a plurality of crack line units connected to each other. Each of the plurality of crack line units comprises a plurality of sub-crack lines connected in parallel. In this manner, the efficiency of inspecting for cracks can be improved.
