Abstract
A liquid crystal display device includes a liquid crystal cell having a pair of transparent substrates opposite to each other and a liquid crystal layer provided between the pair of substrates; first and second retardation plates and a first polarizing plate that are sequentially formed on an outer surface of one of the pair of substrates; and third and fourth retardation plates and a second polarizing plate that are sequentially formed on an outer surface of the other substrate of the pair of substrates. Optical characteristics of the liquid crystal cell, the first to fourth retardation plates, and the first and second polarizing plates are set in predetermined ranges.
