Abstract

Provided is a light-diffusing barrier film. The film is an integral film comprising a barrier layer, a base layer and a light-diffusing layer, sequentially. The film can prevent moisture penetration into a device such as an organic light emitting device, and also imparts a light-diffusing function to the device. In particular, the film can have excellent moisture blocking properties even after a roll-to-roll process.
