Abstract

A display device includes a display panel and at least one electronic component connected to the display panel. The display panel includes a display area and a non-display area disposed around the display area on a plane. The non-display area has a first bending line and a second bending line intersecting the first bending line. The display panel includes a circuit layer and a display element layer including display elements. The circuit layer is disposed in the display area, disposed on a different layer than pixel circuits, and electrically connects the at least electronic component and the driving circuit.
