It is an object of the present invention to provide a method for manufacturing a thin phase difference film of a liquid crystal display easily so as not to prevent a liquid crystal from being driven so that cost for manufacturing a liquid crystal display is more reduced than conventionally. A liquid crystal display device according to the present invention has a structure in which phase difference films that have the same function as a conventional phase difference film are formed by using a liquid crystal stabilized with a polymer over a first substrate and a second substrate that have electrodes formed thereover, and a liquid crystal material is interposed between these substrates. In addition to the structure as described above, it is also a feature that the phase difference film formed over the substrate is formed by using a liquid crystal that is stabilized with a polymer including a conductive material.
