Claim Text:
1. A method for the manufacture of a polymer dispersed liquid crystal display, comprising: forming a first light permeable pressure-sensitive adhesive layer on a first base substrate on which a first transparent conductive layer has been formed, wherein the first transparent conductive layer is contacted with the first light permeable pressure-sensitive adhesive layer; forming a second light permeable pressure-sensitive adhesive layer on a second base substrate on which a second transparent conductive layer has been formed, wherein the second transparent conductive layer is contacted with the second light permeable pressure-sensitive adhesive layer; mixing liquid crystals, monomers capable of light polymerization, nanobeads and light initiators thoroughly to form a homogeneous mixture; coating the homogeneous mixture onto the first base substrate; assembling the first base substrate with the second base substrate to form a cell, so that the homogeneous mixture is provided between the first base substrate and the second base substrate by adhering to the first base substrate through the first light permeable pressure-sensitive adhesive layer and adhering to the second base substrate through the second light permeable pressure-sensitive adhesive layer simultaneously in a single step; and exposing the homogeneous mixture to ultraviolet light after the assembling to form the polymer dispersed liquid crystal film, wherein the first light permeable pressure-sensitive adhesive layer and the second light permeable pressure-sensitive adhesive layer are a conductively anisotropic light permeable pressure-sensitive adhesive so that the pressure-sensitive adhesive is conductive in a direction perpendicular to the base substrate but not conductive in a direction transverse to the base substrate, transmittance of the first light permeable pressure-sensitive adhesive layer or the second light permeable pressure-sensitive adhesive layer is more than or equal to 90%.
