We report on the application of vary thin molybdenum trioxide (MoO<inf>3</inf>) film deposited by spin-coating from dilute aqueous solution to the organic light-emitting diodes (OLEDs). The device characteristics with solution-processed MoO<inf>3</inf>were drastically improved in comparison with the device without MoO<inf>3</inf>buffer layer. Luminance and electroluminescent (EL) efficiency were identical to the devices with poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) or vacuum-deposited MoO<inf>3</inf>buffer layer. Also, the barrier height at interface of indium--tin-oxide/organic layer is lowered with insertion of spin-coated MoO<inf>3</inf>. Solution-processed MoO<inf>3</inf>from dilute aqueous solution is promising for the buffer layer in the OLEDs.
