Abstract: A driver includes a stage that includes a first controller, a second controller, and a first output unit. The first controller controls a voltage level of a first node. The second controller controls voltage levels of a second node and a third node to be equal to the voltage level of a first node or an opposite voltage level of the voltage level of the first node, and controls a voltage level of a fifth node to be equal to the opposite voltage level of the voltage level of the first node. The first output unit may output a gate control signal, which has a first voltage when the second node and the third node is in an on-voltage level state, and has a second voltage when the fifth node is in an on-voltage level state.

Abstract: In a pixel of a display device, a back gate control voltage is applied to a back gate electrode of a first transistor that operates as a driving transistor in an anode initialization period, and the back gate electrode of the first transistor is connected to an anode of a light emitting element in a light emitting period. A first transfer line is disposed apart from the first transistor in a first direction. A capacitor pattern is disposed apart from the first transistor in a second direction opposite to the first direction. A second transmission line is disposed between the first transistor and the capacitor pattern.

Abstract: 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.
