Patent number: 7682864Abstract: A method for fabricating an organic electroluminescent device (OLED) includes the following steps. First, a substrate is provided. Next, an anode layer is formed on the substrate. Next, a buffer layer is formed on the anode layer, wherein the buffer layer include a CFx film (fluorinated carbon films) containing carbon-fluoride bonded molecules. Next, a treatment process is performed on the CFx film to convert the carbon-fluoride bonded molecules into carbon-carbon bonded molecules. A plurality of organic layers is formed on the buffer layer. A cathode layer is formed on the organic layer. Because the buffer layer has a better conductivity, the organic electroluminescent device (OLED) of the present invention has a better luminous efficiency.Type: GrantFiled: May 22, 2006Date of Patent: March 23, 2010Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Wen-Jian Shen, Yi-Lung Kao, Shuenn-Jiun Tang, Chih-Kwang Tzen
