GETTERING AGENT, ABSORPTIVE FILM COMPRISING THE SAME AND ORGANIC ELECTRONIC DEVICE (As Amended)

摘要

Provided are a gettering agent, an absorptive film including the same, and an organic electronic device. In detail, the absorptive film including the gettering agent of the present application is provided on the front side and/or back side of the organic electronic device, and effectively absorbs and blocks moisture, thereby improving the lifespan and durability of the organic electronic device. In addition, the gettering agent of the present application uses a moisture absorbent particle having a nano size to secure transparency of the absorptive film, thereby implementing a top emitting device and also absorbing moisture in the atmosphere during the manufacturing process. Therefore, it is possible to solve the problem of losing the total amount of moisture absorption.

主权项

1. A gettering agent comprising a first moisture absorbent particle, which has an average particle size in a range of 10 nm to 100 nm; and a second moisture absorbent particle, which surrounds a surface of the first moisture absorbent particle and has a lower rate of moisture absorption than the first moisture absorbent particle.
