  • Publication number: 20200357775
    Abstract: A light-emitting apparatus and a method for manufacturing the same are provided in which heat dissipation from an LED package to a heat sinking substrate is improved while electrical insulation therebetween is ensured. The light-emitting apparatus includes a circuit board having an opening, an LED package inserted into the opening from the back side of the circuit board and having an edge connected to the back side of the circuit board, and a heat sinking substrate disposed on the back side of the circuit board so as to be in contact with the LED package.

  • Publication number: 20090323004
    Abstract: A space between substrates in a liquid crystal optical modulator can be sealed with a metal by using a simple configuration. In a seal structure between the substrates constituting a liquid crystal cell in a liquid crystal optical modulator, metal members are provided on the opposing surfaces of the two substrates, and the base metal surfaces of the metal members are brought into direct contract and joined. As a result, a low-melting metal such as a solder that has been conventionally introduced into the joint section becomes unnecessary, and a metal seal providing for strong bonding can be formed with a simple configuration. The liquid crystal optical modulator has a first substrate having a first electrode pattern including a pixel electrode, a second substrate having a second electrode pattern including a counter electrode, and a metal seal disposed so as to be sandwiched between the first substrate and the second substrate.

  • Patent number: 7053971
    Abstract: In a liquid crystal display panel, connecting wires, having a two-layer structure formed of an indium-tin oxide (ITO) layer and a low-reflection metal layer each, are formed in a image non-display section on an upper substrate, while a shielding layer is formed in the image non-display section on a lower substrate. The gap between the upper and lower substrates is made uniform in both an image display section and the image non-display section by adjusting the thickness of the shielding layer relatively to that of the color filter layer formed in the image display section on the lower substrate or by adjusting the diameter of spacers arranged in the image non-display section relatively to that of spacers arranged in the image display section.
