POLYMER DISPERSED LIQUID CRYSTAL FILM CAPABLE OF CONTROLLING PHASE DELAY CHARACTERISTICS OF POLARIZED LIGHT

WIPO Patent Application WO/2013/137632

A1

The present invention relates to a polymer dispersed liquid crystal film capable of controlling the phase delay characteristics of polarized light. The polymer dispersed liquid crystal film is capable of controlling the phase delay characteristics of incident polarized light by comprising: two transparent substrates formed with transparent electrodes on respective side surfaces and arranged in such a manner that the transparent electrodes face each other; a polymer dispersed liquid crystal layer in which polymers and liquid crystals are dispersed at a predetermined composition ratio, wherein the polymer dispersed liquid crystal layer is formed between the transparent substrates in which the transparent electrodes are formed; and a liquid crystal alignment film disposed between the polymer dispersed liquid crystal layer and at least one of the transparent substrates so that the liquid crystals of the polymer dispersed liquid crystal layer are arranged to have orientation. The polymer material constituting the polymer dispersed liquid crystal layer is 40 to 80 percent of the total weight thereof. The transparent electrode is patterned in such a manner that the phase delay can be selectively controlled in certain areas.
