A display panel includes a substrate, a display area, N data lines, first switches, second switches, third switches, and fourth switches. A first peripheral circuit zone, a second peripheral circuit zone, and a display area are defined on a first surface of the substrate, and located between the first peripheral circuit zone and the second peripheral circuit zone. A display area circuit is located in the display area. Each of the N data lines crosses the display area circuit from the first peripheral circuit zone to the second peripheral circuit zone, and N is a positive integer greater than 1. The first switches are located in the first peripheral circuit zone. The second switches are located in the first peripheral circuit zone. The third switches are located on the first surface. The fourth switches are located in the second peripheral circuit zone.

Display panel and method for verifying data lines thereon

A test cell structure of a display panel is disposed in the peripheral region of the display panel. First conductive lines and second conductive lines extend from the display region to the peripheral region, and the amounts of the first and second conductive lines are the same. The test cell structure includes a plurality of first test transistors, a plurality of second test transistors, and a plurality of first shorting bars. The drains of the first test transistors are electrically connected to the first conductive lines respectively, and their sources are electrically connected to the first shorting bars. The sources of the second test transistors are electrically connected to the drains of the first test transistors respectively, and their drains are electrically connected to the second conductive lines. The first test transistors are disposed between the second test transistors and the display region.
