摘要： A display apparatus includes a substrate, a display element, an inorganic insulating layer, a first inorganic encapsulation layer, a dam, a first wire, and a power supply line. The substrate includes a display region. The display element is arranged on the display region. The inorganic insulating layer is arranged between the substrate and the display element. The first inorganic encapsulation layer includes a contact region that directly contacts the inorganic insulating layer. The dam surrounds the display region and includes a dam section that is arranged between the display region and the contact region. The first wire crosses the dam and may transmit a first signal toward the display region. The power supply line crosses the dam, overlaps the first wire, and includes protrusions. The protrusions protrude from an edge of the power supply line and overlap the contact region.
