Abstract
A liquid crystal display device having excellent liquid crystal vertical alignment properties, good transparency when a voltage is applied and good scattering properties when no voltage is applied, and good adhesion with the liquid crystal layer. The liquid crystal display device has a liquid crystal layer formed by irradiating and curing with ultraviolet rays a liquid crystal composition containing a liquid crystal and a polymerizable compound disposed between a pair of substrates provided with electrodes, and at least one of the substrates is provided with a liquid crystal alignment film to vertically align a liquid crystal. The liquid crystal composition contains a compound represented by the formula [], and the liquid crystal alignment film is obtained from a liquid crystal alignment treating agent containing a polymer having a side chain structure represented by the formula [-] or formula [-], and a side chain structure represented by the formula [
