  • Publication number: 20110228401
    Abstract: A body antireflection layer is provided on a display surface of a display device body. A first antireflection layer and a second antireflection layer are provided on both sides of an optical filter that is opposed to the display surface by a predetermined gap. A light-blocking screen frame layer is provided on the optical filter between a light-transmissive base and the first antireflection layer near the display surface at a peripheral area corresponding to an outer periphery of the display device body. A color difference between a position of the screen frame layer and a position of a display area of the display device body is 40 or less. A border between the display area and the screen frame layer becomes difficult to be visible, so that the optical filter can be recognized by users as an integral surface having no border over the entire surface of the optical filter.
