摘要:
By introducing new concepts into a structure of a conventional organic semiconductor element and without using a conventional ultra thin film, an organic semiconductor element is provided which is more reliable and has higher yield. Further, efficiency is improved particularly in a photoelectronic device using an organic semiconductor. Between an anode and a cathode, there is provided an organic structure including alternately laminated organic thin film layer (functional organic thin film layer) realizing various functions by making an SCLC flow, and a conductive thin film layer (ohmic conductive thin film layer) imbued with a dark conductivity by doping it with an acceptor and a donor, or by the like method.

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.

A method of manufacturing a light emitting device of upward emission type and a thin film forming apparatus used in the method are provided. A plurality of film forming chambers are connected to a first transferring chamber. The plural film forming chambers include a metal material evaporation chamber, an EL layer forming chamber, a sputtering chamber, a CVD chamber, and a sealing chamber. By using this thin film forming apparatus, an upward emission type EL element can be fabricated without exposing the element to the outside air. As a result, a highly reliable light emitting device is obtained.

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.
