Abstract:
A method for producing a reflection-type liquid crystal display device, including a first substrate; a second substrate; and a display medium layer interposed between the first substrate and the second substrate, wherein the first substrate includes a first electrode for applying a voltage to the display medium layer; the second substrate includes a second electrode for applying a voltage to the display medium layer; the first substrate includes a light reflective section in the vicinity of the display medium layer for reflecting light which is incident on the reflection-type liquid crystal display device through the second substrate, and includes a plurality of terminal sections for supplying a voltage to the first electrode and the second electrode; and at least one of the plurality of terminal sections has a top layer formed of ITO, only a flat area of a top surface of the top layer being exposed, the method comprising 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, wherein 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.
