Liquid crystal display device

A liquid crystal display device having a reflective part and a transmissive part in each of a plurality of pixels which are arrayed in a matrix, comprising:

• a liquid crystal display panel which is configured such that a liquid crystal layer is held between a pair of substrates, and to which an OCB mode is applied;
• and
• a pair of optical elements which are disposed on outsides of the liquid crystal layer, and optically compensate a retardation of the liquid crystal layer in a predetermined display state in which a voltage is applied to the liquid crystal layer,
• wherein the optical element is configured to include a circular polarization element including a polarizer and a first retardation plate which is disposed between the polarizer and the liquid crystal layer and imparts a retardation of ¼ wavelength, and
• the first retardation plate has such wavelength dispersion characteristics as to establish a relationship, α1<1, where α1 is a ratio of an in-plane retardation Re430 at a wavelength of 430 nm to an in-plane retardation Re550 at a wavelength of 550 nm.
