Display device

Abstract

A display device includes a flexible display panel, a substrate, a cover plate, a first connector, and a first adhesive layer. The substrate is located on the bottom side of the flexible display panel and has a normal direction and a first direction and a second direction perpendicular to the normal direction, the first direction being perpendicular to the second direction. The cover plate is located on the top side of the flexible display panel. The first adhesive layer is located between the cover plate and the flexible display panel. The two first sides of the flexible display panel extend in directions parallel to the second direction. The bending axis of the flexible display panel is parallel to the first direction, and the display surface of the flexible display panel is adapted to convex outward in a direction away from the substrate. The first adhesive layer includes two opposing third sides, the two third sides being parallel and aligned with the two first sides. In the first direction, the length of the cover plate is greater than the length of the first adhesive layer.
