Abstract:
    A multilayer optical film comprising two layers with different optical characteristics alternately laminated in many layers. A production method therefore comprising first injecting ultraviolet-curing liquid crystal into between a pair of glass substrates with transparent conductive films, then applying coherent ultraviolet rays having parallel light fluxes to the ultraviolet-curing liquid crystal from the opposite sides thereof through glass substrates, and, with an electric field being applied to between the pair of transparent conductive films, applying a ultraviolet ray having a uniform intensity on the surfaces of the glass substrates to the ultraviolet-curing liquid crystal through glass substrates.
