Abstract
A method for producing a reflection-type liquid crystal display device includes the steps of forming an ITO layer in the first substrate; patterning the ITO layer to form the top layer in the at least one of the terminal sections; forming a first protective layer so as to cover the top layer; forming a metal layer mainly formed of aluminum so as to cover the first protective layer; and at least partially removing the metal layer and the first protective layer to form a reflective section from the metal layer and expose only the flat area of the top surface of the top layer in the at least one of the terminal sections. Before the step of forming the first protective layer, only the flat area of the top surface of the layer is exposed in at least one of the terminal sections so as to allow the first protective layer to contact the top layer along only the flat area.
