Abstract:
A reflective film display device including first and second display units to which a driving signal is supplied, the second display unit being stacked on the first display unit, and each of the first and second display units comprising:a stationary electrode; a plurality of movable cantilevers, each configured to be elastically deformed, electrically insulated from the stationary electrode, having a first free end and a movable display piece provided at the first free end, and being arranged to have a gap between the first free end and the stationary electrode; a wiring board including conducting lines configured to supply the driving signal to the stationary electrode and the movable cantilevers; a plurality of stationary cantilevers, each having a second free end and a stationary display piece provided at the second free end and arranged on the corresponding movable cantilever, the stationary display piece facing to the movable display piece with a gap between the stationary display piece and the movable display piece; and an alignment structure configured to align the second display unit with the first display unit, to hold the movable and stationary cantilevers substantially in an array and to fix the wiring board to the stationary electrode, said alignment structure including a first aligning member connecting the conducting lines to the stationary electrode and the movable cantilever and a second aligning member positioning the second display unit on the first display unit such that the movable and stationary display pieces of the first and second display units are arranged to form a grid, and the movable cantilever being bent upon application of the driving signal to the conducting lines such that the movable display piece of the second display unit is displaced to a position behind the stationary display piece of the first display unit.
