Abstract: A flexible display panel is disclosed. The flexible display panel includes a substrate and a pixel unit on a first surface of the substrate. An encapsulation layer is on the first surface of the substrate and covers the pixel unit. A support member is on a second surface of the substrate that is opposite the first surface. The support member overlaps an edge of the encapsulation layer. The support member reduces stress applied to areas of the flexible display panel that are vulnerable to cracking during bending of the flexible display panel.
