摘要： PROBLEM TO BE SOLVED: To reduce a drive voltage by doping a doping material which is stable in the atmosphere and can be vacuum deposited to a hole injection layer in an organic EL element composed by forming an anode on a substrate, the hole injection layer right above it and an organic layer including a light emitting layer and a cathode on its upper part further. SOLUTION: For the hole injection layer 30, the doping material comprising a compound which has an electron attractive group and is not to be altered even exposed to the atmosphere is doped, and it is formed by vacuum deposition. Further, by performing heating to be the glass transition temperature of a hole injection transport material constituting the hole injection layer 30 or higher, a hole injection barrier between the anode 20 and the hole injection layer 30 is reduced compared to the case of not doping the doping material to the hole injection layer 30.

摘要： PROBLEM TO BE SOLVED: To prevent a triphenylamine derivative constituting a low molecule material layer from being dissolved away.SOLUTION: As an organic solvent in forming a luminescent layer, an organic solvent having a Hansen solubility parameter Δδof 90 or more is selected. Drying treatment is performed under the temperature which is higher than a solidification point of the organic solvent preferably, equal to or lower than an atmospheric temperature and is lower than the atmospheric temperature by 10°C or more preferably. Thus, when forming a low molecule material layer from a triphenylamine derivative, even in the case where a luminescent layer which becomes another organic film is formed on a top layer, the triphenylamine derivative can be prevented from being dissolved way into the organic solvent. Therefore, surface roughness of the low molecule material layer or the luminescent layer can be suppressed and leak generation or characteristic reduction of an organic EL element can be prevented.
摘要翻译：要解决的问题：防止构成低分子材料层的三苯胺衍生物被溶解。溶解性：作为形成发光层的有机溶剂，选择Hansen溶解度参数＆Dgr;δ为90以上的有机溶剂。干燥处理在比有机溶剂的凝固点高的温度下进行，优选为等于或低于大气温度，并且低于10℃或更优选的气氛温度。因此，当从三苯基胺衍生物形成低分子材料层时，即使在顶层上形成另一有机膜的发光层的情况下，也可以防止三苯胺衍生物溶解在有机溶剂中。因此，可以抑制低分子材料层或发光层的表面粗糙度，并且可以防止有机EL元件的泄漏产生或特性降低。

摘要： PROBLEM TO BE SOLVED: To provide an organic EL display device, capable of acquiring display with no unevenness of luminance at each pixel group when an images is displayed on the two pixel groups respectively, and a driving method thereof.SOLUTION: A driver IC 12 controls lighting time of each of organic EL pixels 13 and 14 so that a product of current density (=driving current/pixel area) flowing through the organic EL pixels 13 and 14 and the light time of the organic EL pixels 13 and 14 becomes constant.
