Abstract:
An optical film laminate comprises: a phase retardation layer; a polarizing layer laminated on the phase retardation layer; and a barrier layer disposed between the phase retardation layer and the polarizing layer or under the phase retardation layer. Iodine migrated from the polarizing layer is blocked by the barrier layer, and thus metallic members included in an image display device can be protected from corrosion.
