Abstract: A liquid crystal display includes at least two liquid crystal display units that are stacked up one another. Each liquid crystal display unit comprises, from top to bottom, a first polarizer, a first substrate, a first pile layer, a liquid crystal layer, a second pile layer, a second substrate, and a second polarizer. The liquid crystal layer has a twist angle of zero or greater than zero. All of the first polarizer, the first substrate, the first pile layer, the liquid crystal layer, the second pile layer, the second substrate, and the second polarizer in each said liquid crystal display unit are adhered to each other by means of whole-face bonding by transparent or non-transparent glue. Alternatively, all of the first polarizer, the first substrate, the first pile layer, the liquid crystal layer, the second pile layer, the second substrate, and the second polarizer in each said liquid crystal display unit are adhered to each other by means of peripheral-bonding by transparent or non-transparent glue.
