An organic electroluminescent device includes an organic compound layer containing luminescent sections placed between substantially transparent electrodes. To prevent the formation of defects in the weld interface between the blades and the disc a shielding gas is used. Radiation conductors having the same configuration are formed according to, for example, a printing technique, and are disposed on the corresponding four side surfaces of the dielectric member while being tilted at 45. The clutch selectively transfers rotation of the clutch roller to the drive roller to drive the conveying surface. The present invention is applicable to a variety of embodiments including video poker machines, black jack machines or other gaming and gambling machines, as well as other systems that include a display mechanism and an activity that can be monitored. The second display panel includes a light emitting element displaying a color, an insulating layer disposed on the light emitting element and including a rubbed surface, a polarization layer disposed on the insulating layer and opposite to the light emitting element with respect to the insulating layer, and a common electrode disposed on the polarization layer and facing the pixel electrode.
