To suppress the increase of production cost caused by increased man hours required for formation of a reflection film in forming a liquid crystal display device with the reflection film by gang printing using a large sized substrate.

In forming the liquid crystal display device with the reflection film by gang printing using the large sized substrate, the reflection film 25 is formed at a stroke on the large sized substrate 22 over the full surface except for a peripheral part 22b with vapor-deposition, sputtering or the like in a state of pressing the peripheral part 22b, an alignment mark M2 is arranged on the peripheral part 22b in the subsequent step and is used for positioning of patterns of an electrode 8 or the like.
