  • Patent number: 10061152
    Abstract: According to one embodiment, a display device includes a display module including a peripheral area located outside a display area, a cover member including a phototransmissive region and a light-shielding region, and a ultraviolet-cured resin layer which bonds the display module to the cover member, includes first and second portions, and contains polar monomers as a monomer component. A transparent first electrode is interposed between the cover member and the display module to cover the phototransmissive region. A second electrode is separated from the first electrode and extends along the first electrode in an area corresponding to the peripheral area. The first and second electrodes apply an electric field to the part of the first portion to orient the polar monomers.
