A client signal having a constant bit rate is segmented every a bytes to create code information blocks. An underlying n-type GaN layer is grown on a sapphire substrate, and a growth mask made from SiO2 film or the like is formed on the underlying n-type GaN layer. The ETT has program guide information for an n-hour span and has a transmission interval. At least one resiliently compressible protrusion is provided between the electrical component and the closed end of the recess so as to be resiliently compressed therebetween into its compressed state when the electrical component is locked in the recess in its locking position. The thin films having a reflecting function are formed from an amorphous alloy, whereby there can be provided an organic EL light-emitting device having reflective films that have all of a reflecting function, a function of shielding transistors from light, and an electrode function, and moreover have little surface unevenness.
