Abstract: A display panel includes: a light emitting element, a driving switching element, a bias switching element and a bias control switching element. The driving switching element is configured to apply a driving current to the light emitting element. The bias switching element is connected to a first electrode of the driving switching element and configured to apply a bias voltage to the first electrode of the driving switching element. The bias control switching element is connected to a first electrode of the bias switching element and configured to apply the bias voltage to the first electrode of the bias switching element.

Abstract: A display panel includes a base layer including a component area, a circuit layer disposed on the base layer, and a light emitting device layer including a first light emitting device disposed in the component area. The circuit layer includes first conductive patterns each extending in a first direction, at least one first intermediate insulating layer disposed on the first conductive patterns, and second conductive patterns disposed on the at least one first intermediate insulating layer and each extending in a second direction intersecting the first direction. Each of the first conductive patterns and the second conductive patterns overlap the first light emitting device in a plan view.
