  • Publication number: 20140085729
    Abstract: There is provided an optical filter or an anti-reflection structure with lower reflection in comparison with the conventional ones by comprising a gradient refractive index thin film 12 with continuous, periodic refractive index change in the film thickness direction and a fine periodic structure 151 lowering reflection, wherein the refractive index of the gradient refractive index thin film 12 in its thickness direction on the substrate side changes so as to become close to that of the substrate, while on the fine periodic structure 111 changes so as to become close to that of the fine periodic structure 151. The optical filter can be used in an optical device or an electronic device display.

  • Publication number: 20140071537
    Abstract: A display apparatus has a display panel that includes a display area and a boundary area, a window that protects the display panel and that transmits an image that is realized in the display area, and an adhesion layer that adheres the display panel and the window. The window includes a window body with a first surface that faces the display panel and a second surface that is externally exposed, a light-shielding member that is on the first surface and that blocks the boundary area of the display panel from being externally visible, and a light-shielding member protection layer that is between the light-shielding member and the adhesion layer, and that protects the light-shielding member.

  • Patent number: 8665384
    Abstract: A coated article includes a low-E coating supported by a substrate (e.g., glass substrate), the low-E coating including first and second IR reflecting layers comprising silver and/or gold, and at least one UV blocking layer that blocks significant amounts of UV light having a wavelength of from 380-400 nm so that no more than about 20% of light having a wavelength of from 380-400 passes through the low-E coating. The UV blocking layer may be positioned so as to not directly contact the first and second IR reflecting layers.

  • Patent number: 8622556
    Abstract: A frame-attached anti-reflection glass (a cap for optical device) includes a plate-shaped member including an anti-reflection film formed on at least one surface of a plate-shaped glass, and a frame-shaped member made of silicon joined to a peripheral portion on one surface side of the plate-shaped member. The anti-reflection film includes two partial films having different compositions, and one partial film is a light-absorbent film. The two partial films are continuously formed on the plate-shaped glass, and respective surfaces of each partial film are on a level with each other. The plate-shaped glass and the frame-shaped member (silicon) are joined together by anodic bonding.
