  • Patent number: 11968789
    Abstract: A display device includes a front display area (FDA), side display areas (SDAs), and a corner display area (CDA). The SDAs and the CDA are disposed outside of the FDA. The SDAs include: a first SDA disposed at a first side of the FDA; and a second SDA disposed at a second side of the FDA. The CDA is disposed at a corner of the FDA between the first SDA and the second SDA. The CDA is connected to the first SDA and the second SDA. The FDA has a flat display surface. The first SDA, the second SDA, and the CDA respectively form a bent surface. A shape of the bent surface of the CDA is different from a shape of the bent surface of the first SDA and a shape of the bent surface of the second SDA. The CDA is stretchable and/or shrinkable.
