Absorbent and passivation layer for optical element comprising the same

摘要

The present invention relates to an absorbent and a passivation layer for an optical element comprising the same, and more specifically to an absorbent that can be applied to a flexible substrate while blocking the inflow of water, and also not blocking light, and a passivation layer for the optical element comprising the same. Also the present invention relates to an absorbent that can maintain a light-emitting property for a long period of time by minimizing damage to the optical element by using the compound synthesized using a non-polar solvent, and the passivation layer for the optical element comprising the same.
