Abstract: Fabrication device of organic light emitting diode (OLED) includes a Substrate, a transparent conductive layer, an insulating film layer, an organic light-emitting layer, and a conductive layer; when a suitable potential is applied thereto, an organic light-emitting layer emits a visible light, however, it usually occurs breakdown between cathode and anode or bad signal, therefore, the present invention provides a positive insulating film photoresist with an easily inclining obtuse angle, smooth surface, and easily controlled fabrication condition to cover the edge of a transparent electrode (anode) in order to avoid that when the edge of ITO transparent electrode is sharp it causes an organic light-emitting layer film breakdown and results from signal lost or weaken to increase the yields.

Abstract: An organic EL device includes an anode, a cathode and an EL element arranged between the two. The EL element includes a substance represented by the following chemical formula: in which m, n=1-3; the substitute R is selected from a group consisting of t-butyl, phenyl, methylphenyl, naphehyl and heterocyclic compound. The EL element is highly efficient, lower-voltage operative and easy to be synthesized.

Abstract: The present invention discloses a novel compound useful as the material for a red organic EL device. The novel compound is produced by connecting a benzene ring at the positions 2 and 3 of withdrawing group 2,5-dimethyl-4-(2,2-dicyano)pyrane, and connecting a conjugated donating group at position 5. Using this compound, the EL emission is shifted to the red spectral region, and a higher purity in color for red EL elements is obtained. The synthesis of the compound is easy and the product yield is improved compared to the prior art. Moreover, the red organic EL devices fabricated using the compound have properties that conform with existing NTSC standards.
