Abstract: A flexible display panel and a display apparatus including the flexible display panel are disclosed. The flexible display panel includes an encapsulated panel, a first protective film on one side of the encapsulated panel, and a second protective film on another side of the encapsulated panel. The encapsulated panel includes a flexible panel and a flexible encapsulation member on the flexible panel. The flexible panel includes a first region on a first plane and that includes a display region, and a second region on a second plane that is bent with respect to the first plane and that includes a non-display region. The flexible encapsulation member encapsulates the display region. The display apparatus also includes a support unit for maintaining a shape of the flexible panel.

Abstract: A display substrate and a display device including the display substrate are disclosed. In one aspect, the display substrate includes a plurality of pixels formed in a substantially circular pixel area and a driving circuit formed in a peripheral area surrounding the pixel area and configured to drive the pixels. A boundary is formed between the pixel area and the peripheral area, and the boundary is substantially concentric with respect to an arc defining the substantially circular pixel area. The driving circuit comprises a conductive pattern having a first side which extends in a peripheral direction crossing the boundary.
