  • Patent number: 10686161
    Abstract: A display device includes a display panel, a first film, and a second film. The display panel includes a light emitter to emit light including display information, a first surface, and a second surface opposite to the first surface. The light passes through a second surface. The first film is on the first surface of the display panel. The second film is on the second surface of the display panel. The display panel includes a side surface that connects the first surface and the second surface. A side surface of the second film protrudes outwardly more than a side surface of the first film with respect to the side surface of the display panel. The side surface of the second film is inclined at an angle greater than about 90 degrees with respect to the second surface.
