Method of manufacturing polymer dispersed liquid crystal

A method of manufacturing polymer dispersed liquid crystal, the method comprising:

• mixing liquid crystal, a first photopolymerizable material, a first photoinitiator, a second photopolymerizable material and a second photoinitiator to form a mixture, wherein the first photoinitiator is configured to initiate polymerization of the first photopolymerizable material by irradiating a first ultraviolet light, and the second photoinitiator is configured to initiate polymerization of the second photopolymerizable material by irradiating a second ultraviolet light, and the first ultraviolet light has a wavelength different from a wavelength of the second ultraviolet light;
• polymerizing the first photopolymerizable material of the mixture by irradiating the first ultraviolet light to form a plurality of first liquid crystal droplets;
• and
• polymerizing the second photopolymerizable material of the mixture by irradiating the second ultraviolet light to form a plurality of second liquid crystal droplets dispersed between the first liquid crystal droplets, wherein each of the second liquid crystal droplets has a particle size less than or equal to a particle size of each of the first liquid crystal droplets.
