ABSTRACT:
An object of the present invention is to provide a liquid crystal display device free from color displacement and having improved contrast ratio as well as an improved aperture ratio. The object is attained by the following structure comprising a substrate having a pixel electrode and a driving element, liquid crystal layers stacked on a substrate, a transparent pixel electrode interposed between the stacked liquid crystal layers, and a driving element provided on the substrate. The transparent pixel electrode is electrically connected to the driving element through an opening formed in a specified region of the liquid crystal layer. Each of the liquid crystal layers is composed of microcapsules each containing a liquid crystal and a binder for binding the microcapsules. An insulating layer is provided between the pixel electrode on the substrate and the liquid crystal layer or between the pixel electrode interposed between the liquid crystal layers and the liquid crystal layer. The wall films of the microcapsules, the binder, and the insulating layer are composed of a photosensitive polymer material.
