  • Publication number: 20230171902
    Abstract: A display device having a display panel including first and second folding areas, a first non-folding area between the first and second folding areas, and a second non-folding area. A panel support is disposed on a lower side of the display panel and includes a first lattice pattern overlapping the first folding area, a second lattice pattern overlapping the second folding area, a first flat plate overlapping the first non-folding area, and a second flat plate overlapping the second non-folding area. An adhesive member is interposed between the display panel and the panel support and includes a first adhesive member disposed directly on the first flat plate and a second adhesive member disposed directly on the second flat plate. An adhesive force between the first adhesive member and the first flat plate is greater than an adhesive force between the second adhesive member and the second flat plate.
