Abstract
A display panel includes a display region, a connecting region, a pad region, and an extension region. The display region includes a plurality of scan lines and a plurality of data lines. The connecting region is formed with first and second connecting line units, each of which is electrically coupled to the scan lines and data lines. The pad region is formed with first and second pad units, each of which extends from the first and second connecting line units. The extension region is formed with an extension line unit that extends from the first pad unit. A testing method for a display panel is also disclosed.
