Organic electroluminescent devices and luminescent display employing such organic electroluminescent devices

An electroluminescent element which comprises an optically transparent substrate, an anode, an organic hole transport layer, an organic electron transport layer, and a cathode, which are sequentially arranged one over another, said organic hole transport layer serving as the main luminescent zone and containing quaterterrylene or a derivative thereof.

An electroluminescent element which comprises an optically transparent substrate, an anode, an organic hole transport layer, an organic electron transport layer, and a cathode, which are sequentially arranged one over another, said organic electron transport layer serving as the main luminescent zone and containing quaterterrylene or a derivative thereof.

An electroluminescent element which comprises an optically transparent substrate, an anode, an organic hole transport layer, an organic electron transport layer, and a cathode, which are sequentially arranged one over another, said organic electron transport layer (which functions also as the luminescent layer) serving as the luminescent zone and containing quaterterrylene or a derivative thereof.

An electroluminescent element which comprises an optically transparent substrate, an anode, an organic hole transport layer, an organic electron transport layer, and a cathode, which are sequentially arranged one over another, said luminescent layer serving as the luminescent zone and containing quaterterrylene or a derivative thereof.

A self-luminous display emitting three primary colors of red, green, and blue, characterized in that light is emitted from an electroluminescent element composed of a cathode, an anode, and an organic layer which contains the luminescent zone and is held between said cathode and anode and said luminescent zone contains as the luminescent material quaterterrylene or a derivative thereof.
