摘要： A display device includes a first layer disposed on a base layer and including a first gate electrode, a first gate insulating layer, and an active layer, and a second layer disposed on the first layer and including a second gate electrode, a second gate insulating layer, and the active layer. The first layer and the second layer share the active layer. The first gate insulating layer has a first dielectric constant, and the second gate insulating layer has a second dielectric constant. The first dielectric constant and the second dielectric constant are different from each other.

摘要： A display device comprises a thin film transistor layer comprising a first metal layer disposed on a substrate and a thin film transistor disposed on the first metal layer, first and second electrodes disposed in a display area on the thin film transistor layer and extending in parallel in a direction, a plurality of light emitting elements disposed between the first and second electrodes, and an alignment line disposed in a non-display area disposed adjacent to the display area and electrically connected to the first and second electrodes. The alignment line comprises metal patterns disposed in the first metal layer and spaced apart from each other, and a bridge portion disposed on the first metal layer and electrically connected to the metal patterns.

摘要： A display device includes a first transistor, a pixel electrode electrically connected to the first transistor, and a second transistor electrically connected to the first transistor. A nitrogen content per unit area of an active layer of the second transistor is greater than a nitrogen content per unit area of an active layer of the first transistor.
