  • Patent number: 11455048
    Abstract: A display device includes a display panel, a touch panel, and a digitizer. The digitizer includes a first electrode pattern layer, a first cover layer that is thermally deformable at a first thermal deformation temperature or higher, and a first intermediate layer located between the first electrode pattern layer and the first cover layer. The first intermediate layer is thermally deformable at a second thermal deformation temperature or higher. The second thermal deformation temperature is lower than the first thermal deformation temperature.
