Abstract: A display device includes a substrate that includes a display area and a non-display area, a display layer disposed on the substrate and overlapping the display area, and a support plate disposed under the substrate. The support plate includes a first region disposed on a rear surface of the display layer, a second region connected to the first region and including a lattice pattern, and a third region connected to the second region and disposed on a rear surface of the first region. The second region is bent and overlaps a bending area of the non-display area of the substrate.

Abstract: A display device includes a substrate including a bending area, a flat area adjacent to the bending area, and first and second surfaces opposite to each other, a display unit corresponding to the flat area and on the first surface, a support layer which is on the second surface of the substrate, corresponds to the flat area, and is disconnected at the bending area to define an end portion closest to the bending area, and the substrate defining a groove in the bending area. The end portion of the support layer is bendable together with the substrate and includes a flat portion corresponding to the flat area of the substrate, and a bending portion corresponding to the bending area of the substrate. The substrate which is unbent disposes the bending portion having an acute angle of inclination with respect to the second surface of the substrate.
