Abstract

A method of manufacturing a PDLC type light control body using long-wavelength light includes the steps of: preparing a liquid crystal composition for manufacturing the PDLC type light control body; applying the liquid crystal composition between two transparent substrates, each being provided thereon with a transparent electrode layer, to form a liquid crystal composition layer therebetween; and irradiating the liquid crystal composition layer formed between the two transparent substrates with light having a wavelength range of 380 ~ 460 nm to photocure the liquid crystal composition layer.
