Organic light emitting diode device

摘要

An organic light emitting diode device includes a first electrode, a second electrode, and an emission layer disposed between the first and second electrodes. The first electrode includes a first layer and a second layer. The first layer includes ytterbium (Yb), samarium (Sm), lanthanum (La), yttrium (Y), calcium (Ca), strontium (Sr), cesium (Cs), ruthenium (Ru), barium (Ba), or a combination thereof and having a thickness ranging from about 40 to 200 Å. The second layer includes silver (Ag), aluminum (Al), copper (Cu), chromium (Cr), or a combination thereof and having a thickness ranging from about 100 to 250 Å.
