A communication system is disclosed that allows high data-rate transmission of data between components. The technique uses virtualization of memory space to map a virtual address space to a larger physical address space wherein no memory bank conflicts will occur. When the organic electroluminescent element is formed using a dopant as an emitting material, the asymmetric arylamine derivative exhibits superb emission efficiency and an excellent lifetime characteristic in a blue wavelength region. , and at least one kind of a photoinitiator for initiating cationic curing.
