Abstract
In a movable shutter-system display device, a movable shutter includes an amorphous silicon film material which has a low residual stress and thus is stable. A display device includes a display panel comprising a first substrate and a second substrate. The display panel includes a plurality of pixels; each of the plurality of pixels includes a movable shutter including amorphous silicon and a driving circuit for driving the movable shutter; and the amorphous silicon included in the movable shutter is formed of at least two amorphous silicon films, and where any two amorphous silicon films adjacent to each other among the at least two amorphous silicon films are a first amorphous silicon film and a second amorphous silicon film stacked on the first amorphous silicon film, the first amorphous silicon film and the second amorphous silicon film have different characteristic values.
