Abstract:
1. An organic electroluminescent display device comprising: a cell including at least one carrier-transporting layer comprising a liquid crystal substance and at least one organic luminous layer sandwiched between a transparent electrode and a backside electrode each held in parallel to the other, the other; a substrate having two surfaces, the cell being laid on one surface of the substrate; and a polarizing plate laid on the other surface of the substrate, wherein a layer adjacent the liquid crystal substance is an oriented layer; and wherein said display device is driven as a liquid crystal display device at a voltage lower than a light emission initiating potential of the organic luminous layer or as an electroluminescent display device at a voltage higher than the light emission initiating potential of the organic luminous layer in response to magnitude of an applied voltage.
