    摘要: There is provided an electroluminescent element using a material that is excellent in film forming properties and carrier transporting properties, emits a light in the solid state, and can be suitably used also as a host material. The electroluminescent element has an electroluminescence layer between a couple of electrodes, and a complex of a Group 4 metal of the periodic table, which is excellent in the film forming properties and the carrier transporting properties and capable of emitting a light in the solid state, is used in a part of the electroluminescence layer to form the electroluminescent element. The complex of a Group 4 metal of the periodic table has an emission wavelength on a longer wavelength side as compared with conventional host materials such as Alq3, and thereby may be combined with a red light emitting guest material to form a light emitting layer.

    摘要: An EL element which is thicker and lower-voltage drive without doping acceptor or donor than the conventional one. An EL element in which an electroluminescent film 103 containing an organic compound which can provide electroluminescent, a floating electrode 104, an electron transport supporting layer 105 and a cathode 102 are in order laminated on an anode 101. A film thickness of the electroluminescent film 103 is on the order of a conventional film thickness (on the order of approximately 100 nm), and the electron transport supporting layer 105 may also have a film thickness on the order of the electroluminescent film 103. The EL element can be driven at lower voltage than the conventional one by introducing a hole blocking material into an electron transport supporting layer.

    摘要: The present invention provides a white organic light-emitting element high in the emission efficiency. In particular, the invention provides a white organic light-emitting element that has an emission spectrum having peaks in the respective wavelength regions of red color, green color and blue color and is high in the emission efficiency.Since a spectrum region lowest in the emission efficiency is a red region, by introducing a reddish phosphorescent material, a highly efficient white organic light-emitting element is obtained. At this time, in order to inhibit the reddish phosphorescent material from singularly emitting, as shown in FIG. 1, a distance between a second emission region 114 where a reddish phosphorescent material 124 is a luminescent material and a first emission region 113 that exhibits emission in a shorter wavelength side than the second emission region is separated. In a configuration shown in FIG. 1, it is preferable to use an electron transport material in a layer 115 between the first emission region and the second emission region and more preferable to use a hole block material.
