The present invention provide a light emitting device including: a resin base having a patterned interconnection; an n-type ZnSe substrate mounted on the resin base; an epitaxial light emission structure formed of a compound crystal relating to ZnSe serving as a matrix, formed on the ZnSe substrate and emitting light when an electric current is applied. A specific amplitude and a specific phase are defined in each individual cell. The ceramic oxide layer may be less than 1 micron thick. When having received the initializing signal, each of the third switch devices operating in the member mode constructs a management communication channel with the second switch device operating in the master mode. Multiplexing of arrays and bit-linens results in efficient use of chip area.
