  • Patent number: 8067084
    Abstract: An electromagnetic-wave shielding and light transmitting plate 1 comprising an antireflection film 3, an electromagnetic-wave shielding film 10, a transparent substrate 2, and a near-infrared ray blocking film 5, wherein they are laminated and united by using intermediate adhesive layers 4A, 4B and a pressure-sensitive adhesive 4C, and the peripheries thereof are covered by a conductive sticky tape 7. The electromagnetic-wave shielding film 10 has a conductive foil 11 formed by pattern etching on a substrate film 13, is processed to have antireflection function by forming a light absorbing layer 12 on the conductive foil 11, and is subjected to a matting process to form small irregularities by roughening the surface of the light absorbing layer 12. A display panel is manufactured by bonding this electromagnetic-wave shielding film 10 to the front surface of a plasma display panel body.

  • Patent number: 7214282
    Abstract: An electromagnetic-wave shielding and light transmitting plate 1 having an antireflection film 3, an electromagnetic-wave shielding film 10, a transparent substrate 2, and a near-infrared ray blocking film 5, laminated and united by using intermediate adhesive layers 4A, 4B and a pressure-sensitive adhesive 4C, the peripheries thereof covered by a conductive sticky tape 7. The film 10 has a conductive foil 11 formed by pattern etching on a substrate film 13, is processed for antireflection by forming a light absorbing layer 12 on the conductive foil 11, and is subjected to matting to form small irregularities by roughening the surface of the light absorbing layer 12. A display panel is manufactured by bonding this film 10 to the front surface of a plasma display panel body.
