PURPOSE: A getter composition is provided to improve the lifetime of an organic light-emitting device, to prevent display defects, and to improve display characteristic and lifetime of the organic light-emitting device. CONSTITUTION: A getter composition comprises an absorbent and a binder. The binder has a volatilization degree of 40 ppm or less when heated at 60-120 °C for 2 hours. The binder comprises a silicone resin, epoxy resin or combination thereof. The absorbent has a particle size of 10-500 nm. An organic light-emitting device includes: first and second substrates which are faced to each other; an organic electroluminescent layer located between the first substrate and the second substrate; and a getter(180) which is located between the first substrate and the second substrate and formed of the getter composition.
