  • Patent number: 8294143
    Abstract: A display unit that secures favorable display performance and has a simple structure is provided. The display unit includes a multilayer structure in which an organic light emitting device group respectively having a plurality of organic light emitting devices that emits cyan light and a plurality of organic light emitting devices that emits magenta light and a color filter group having a plurality of blue filters that transmit blue light and a plurality of yellow filters that transmit yellow light are sequentially layered. In the display unit, the cyan light and the magenta light entering from the organic light emitting device group to the color filter group is converted to blue light by the blue filter, and is respectively converted to green light and red light by the yellow filter. Therefore, compared to a case that the organic light emitting device group emits white light, color separation is more facilitated.

    Abstract: A coil bobbin to which an immobilizer coil is mounted, coil connecting terminals to which ends of the coil are connected, a fixed contact, a terminal for the fixed contact and connector terminals are integrally formed by resin molding into a coil bobbin integrated type insulator. Then, the coil connecting terminals, the terminal for the fixed contact, and the connector terminals are respectively soldered to a wiring board. All of them are incorporated in a body. In this manner, stress exerted on the soldered areas between the coil connecting terminals and the wiring board can be moderated to the substantially same extent as stress exerted on the soldered areas between the terminal for the fixed contact and the connector terminals, and the wiring board.
