Patent number: 7195826Abstract: The new organic electroluminescent display device has a carrier-transporting layer and/or an organic luminous layer composed of a nematic liquid crystal or a liquid crystal dispersing a carrier-transporting low-molecule therein. When the organic luminous layer is to be bestowed with faculty as a liquid crystal, it is made of a nematic liquid crystal. Both the carrier-transporting layer and the organic luminous layer may be bestowed with faculty as a liquid crystal. Since the liquid crystal is incorporated in the carrier-transporting layer and/or the organic luminous layer, the display device can be driven as a liquid crystal display device in a dark place by charging with a voltage lower than a light emission initiating potential. Of course, it is driven as an electroluminescent display device when it is charged with a voltage higher than the light emission initiating potential. Use of an electroluminescent liquid crystal as a organic luminous layer enables omission of a carrier-transporting layer.Type: GrantFiled: August 28, 2003Date of Patent: March 27, 2007Assignees: Tohoku Pioneer CorporationInventors: Junji Kido, Hitoshi Nakada, Teruo Tohma, Ryuji Murayama, Toshinao Yuki

Patent number: 6858271Abstract: A conductive organic compound device structure suitable for constituting an electronic device, such as an organic EL device, is formed by including a pair of oppositely spaced electrodes, and a carrier transporting layer disposed between the electrodes and in contact with one of the electrodes. The carrier transporting layer comprises a conductive organic compound having a ?-electron resonance structure in its molecule. In the device, the ?-electron resonance structure plane of the conductive organic compound in the carrier transporting layer is aligned substantially parallel to surfaces of the electrodes. The conductive organic compound is preferably a conductive liquid crystal, such as a discotic liquid crystal or a smectic liquid crystal, and a layer thereof is included in the device, preferably by vacuum deposition.Type: GrantFiled: September 7, 2000Date of Patent: February 22, 2005Assignee: Canon Kabushiki KaishaInventors: Shinjiro Okada, Akira Tsuboyama, Naoya Nishida, Takashi Moriyama
