Abstract: A flexible display panel includes a display area to display an image, and a non-display area disposed outside the display area. The non-display area includes a first portion and a second portion. The first portion extends from the display area, and includes a support layer disposed on a flexible substrate. The second portion extends from the first portion, and is bent from a plane of the first portion. A property of a material of the support layer in the first portion is different than the property of the material of the support layer in the second portion.
