    Abstract: A pixel circuit includes: a driving switching element; a data initializer to initialize a voltage of a control electrode of the driving switching element; a data writer to write a data voltage to the driving switching element; an organic light emitting element; an organic light emitting element initializer to initialize an anode electrode of the organic light emitting element to a second initialization voltage based on an organic light emitting element initialization gate signal; and a light emitting controller to control an emission of the organic light emitting element. The organic light emitting element initializer includes: a control electrode to receive the organic light emitting element initialization gate signal; an input electrode to receive the second initialization voltage; an output electrode connected to the anode electrode; and a conductive layer to receive a compensation control signal that is different from the organic light emitting element initialization gate signal.

    Abstract: A display device may include a light emitting element, a buffer layer, a gate insulation layer, and a switching element. A refractive index of the gate insulation layer may be equal to a refractive index of the buffer layer. The switching element may be electrically connected to the light emitting element and may include an active layer and a gate electrode. The active layer may be positioned between the buffer layer and the gate insulation layer and may directly contact at least one of the buffer layer and the gate insulation layer. The gate insulation layer may be positioned between the active layer and the gate electrode and may directly contact at least one of the active layer and the gate electrode.
