Abstract
A plastic-substrate liquid crystal display device has, on inner faces of a pair of plastic substrates 3 for sandwiching liquid crystals 10, a hard coat 4 made of an organic material, an SiOx undercoat 5, and an ITO electrode 6 in this order. Boron (B) is contained in the material of the hard coat 4. It is thus possible to enhance the adhesion property of the SiOx undercoat 5 and the ITO electrode 6 with respect to the substrate 3 and to prevent the occurrence of cracks therein.
