摘要： According to the present invention, provided is a PDLC film, which includes a PDLC layer excellent in thickness uniformity and is suppressed from causing liquid crystal leakage from the PDLC layer. A method of producing a polymer dispersed liquid crystal film of the present invention includes: applying, to a first transparent conductive film, an emulsion including a solvent, and polymer particles and liquid crystal particles dispersed in the solvent to form an applied layer; drying the applied layer to form a polymer dispersed liquid crystal layer containing a polymer matrix and the liquid crystal particles dispersed in the polymer matrix; and laminating a second transparent conductive film on the polymer dispersed liquid crystal layer, wherein the polymer particles include first polymer particles and second polymer particles, and wherein an average particle diameter of the second polymer particles is larger than an average particle diameter of the first polymer particles.

摘要： The present invention provides a curved display device manufacturing method comprising the steps of: coupling a flat display, a transparent adhesive layer, and flat cover glass, thereby manufacturing a flat display assembly; applying an adhesive to the edge of the flat display assembly; seating the flat display assembly on a curved jig; adsorbing the flat display assembly onto the surface of the curved jig by using vacuum holes formed in the curved jig such that the flat display assembly is bent; and coupling a backlight unit to the adhesive-applied area. The step of coupling a backlight unit to the adhesive-applied area comprises a step of curing the adhesive in a state in which the backlight unit is forced against the display assembly such that the display assembly remains bent.
