Patent ID: 8294849

Claim:
A liquid crystal display device, comprising: a liquid crystal display element comprising (i) a pair of glass substrates facing each other, (ii) transparent electrode patterns, each transparent electrode pattern being formed on a facing surface of a respective one of said pair of glass substrates, (iii) film structures, each film structure including an oriented film and being formed on a respective one of said pair of glass substrates covering said transparent electrode on the respective one of said pair of glass substrates, and (iv) a liquid crystal layer held between the pair of glass substrates; and a light source adapted to radiate near infrared rays to said liquid crystal display element, wherein said liquid crystal layer includes rod-shaped Au particles of nanometer order which are dispersed in said liquid crystal layer and enhance absorption of near infrared rays by said liquid crystal layer; and wherein 0.02 wt % to 1.0 wt % of said Au particles of nanometer order are added to liquid crystals mainly composing said liquid crystal layer, and heat said liquid crystal layer by absorbing the near infrared rays radiated from said light source so as to improve a response speed of the liquid crystal display at a low temperature.
