ABSTRACT:
A liquid crystal display device which includes a first substrate and a second substrate, a liquid crystal layer sandwiched between the first and second substrates, electrodes for applying an electric field to the liquid crystal layer to control a retardation of the liquid crystal layer, a plurality of pixels, and at least one polarizer disposed outside of the first substrate, wherein the first substrate positioned between the polarizer and the liquid crystal layer includes an optical phase compensation means which includes a first region having a first retardation and a second region having a second retardation, whereby a color of emitted light from each of the plurality of regions is selected to be a specific one, in accordance with the retardations of the optical phase compensation means and the retardation of the liquid crystal layer.
