A microshutter array can have a frame, a plurality of linear microshutter elements, and a plurality of electrodes. The frame defines a plurality of openings and each opening is defined by a first sidewall, a second sidewall, a third sidewall opposing and parallel to the first sidewall, and a fourth sidewall. Each opening includes a light-transmissive portion configured to span an area. The plurality of linear microshutter elements are configured to extend across at least a part of the area. Each linear microshutter element can have a blade extending in a length direction across and blocking the light-transmissive portion. Each linear microshutter element can have a neck extending from the blade, and at least one torsion bar connected to the neck and connected to sidewalls of the frame.
