Abstract
A display device includes a display area and a peripheral area surrounding the display area, a thin film transistor in the display area, a first insulating layer, the first insulating layer covering the thin film transistor, a signal line on the first insulating layer, the signal line being coupled to the thin film transistor, a second insulating layer on the first insulating layer, the second insulating layer covering the signal line, a power supply line in the peripheral area, the power supply line configured to supply power to a pixel circuit including the thin film transistor, and a first dam including a multilayer structure on the power supply line and overlapping at least a part of the power supply line, in which multilayer structure including a lowermost layer including the same material as the second insulating layer, and the lowermost layer is above the power supply line.
