Abstract

A flexible display panel has a display area, a bonding area, and a bending area located between the display area and the bonding area. A flexible substrate includes a first surface and a second surface. Signal leads electrically connected to pixel driving circuits pass through the bending area from the display area and extend to the bonding area. In the pixel driving circuits, at least one pattern layer made of an inorganic material and located between the signal leads and the flexible substrate passes through the bending area from the display area and extends to the bonding area. A second organic material layer is disposed on a side of the signal leads away from the first surface and located at the bending area. A groove is disposed in a film layer away from the signal leads, and is located between the display area and the bonding area.
