Abstract

The electrical properties of OLEDs was investigated by the various cathode layer. It was measured by IVL for electrical properties and optical properties by EL spectrum. The structure of OLEDs was ITO/TPD(400$\AA$)/$Alq_3$(600$\AA$)/LiF(5$\AA$)/various cathode layer. The threshold voltage was increased by the deposited Au layer. The luminance was decreased by deposited Au layer.
