A display device includes a substrate including a display area and a non-display area around the display area. A pixel is disposed on the display area. A first dam is disposed on the non-display area. The first dam includes a first sub-dam and a second sub-dam disposed on the first sub-dam. A first power line is disposed on the non-display area and passes between the first sub-dam and the second sub-dam. The first power line is connected to the pixel. A bridge pattern is disposed under the first sub-dam. The bridge pattern is connected to the first power line.

A multi-channel thin film transistor ('TFT') includes: a gate electrode; a semiconductor including a first channel area, which operates within a first driving range and has a first threshold voltage, and a second channel area which operates within a second driving range smaller than the first driving range and has a second threshold voltage, where an absolute value of the second threshold voltage is greater than an absolute value of the first threshold voltage; a first electrode connected to an end of the semiconductor; and a second electrode connected to another end of the semiconductor.
