Abstract
A TEG near the perimeter of a frame region is away from a TFT, which is disposed in a display region and is actually used for screen display. Hence, the characteristics of the TEG can change in a manner different from that in the characteristics of the TFT within the display region. Accordingly, provided is a display device that includes a TEG pattern disposed between the display region and a trench, and includes a dummy pixel circuit disposed between the display region and a barrier wall. The TEG pattern is outside the display region and is adjacent to at least the dummy pixel circuit.
