    Abstract: An organic light-emitting device is disclosed, the organic light-emitting device comprising a first electrode, a second electrode disposed opposite to the first electrode, and an emission layer comprising organic materials and disposed between the two electrodes. The emission layer may include a host and a dopant. The host may be a silane derivative of anthracene having at least one silicon substituent that is an aryl group having at least two rings that are fused to each other. The dopant may be a 7H-benzo[c]fluorene having diarylamino substituents at the 5- and 9-positions. This scheme provides organic light-emitting devices having low driving voltages, high light-emitting efficiencies and long lifetimes.
