Abstract: A curved display apparatus includes an adhesive member, a back frame and a flexible display panel. The back frame includes a curved attaching portion for disposing the adhesive member thereon. The curved attaching portion has a first curvature radius. The flexible display panel is combined with the back frame via the adhesive member. The adhesive member is stretched by the flexible display panel to allow that the flexible display panel elastically returns to have a second curvature radius. The first curvature radius is less than the second curvature radius.
