ORGANIC LED COMPRISING CHELATE METAL COMPLEX

摘要

PURPOSE: An organic LED(Light Emitting Device) comprising a chelate metal complex is provided to improve a charge transfer characteristic by using p-type chelate metal complex and an n-type chelate metal complex. CONSTITUTION: An ITO(Indium Tin Oxide) layer(2) as an anode transparent layer is formed on a glass(1). A hole transfer layer(3) is formed on the ITO layer(2) as the anode transparent layer. A light emitting/electron transfer layer(4) is formed on the hole transfer layer(3). A metal electrode(5) as a cathode is formed on the light emitting/electron transfer layer(4). An organic light emitting device has a stacked structure of the glass(1), the ITO layer(2), the hole transfer layer(3), the light emitting/electron transfer layer(4), and the metal electrode(5). The stacked structure is connected with direct current type power or pulse type power(6). A p-type chelate metal complex and an n-type chelate metal complex are used as the hole transfer layer(3) and the light emitting/electron transfer layer(4), respectively.
