A wire shield has a first tubular section for attachment to a fixed component. The integration component may help to identify the scope of the systems that are to be integrated using a multi-level top-down approach. The base of one of the binding rings is secured to one of the operating piece, and the base of the other binding ring is secured to the other operating piece. These compounds have a coefficient of thermal expansion which corresponds to that of the discharge vessel. In one embodiment, an OLED device includes an EL configured to emit light, a driving TFT configured to control the EL, a storage capacitor coupled to the driving TFT, and at least one insulation layer configured to insulate at least one of the EL, the driving TFT and the storage capacitor, and including a plurality of recesses formed on a surface of the at least one insulation layer.
