An infrared transmission large-area shutter is provided. The infrared transmission large-area shutter includes a first contact layer on a substrate, a plurality of stacks formed in a two-dimensional (2D) array pattern on a first region of the first contact layer, each stack comprising a lower reflection layer, an active layer, an upper reflection layer, and a second contact layer which are formed sequentially in this order on the first contact layer, a first electrode formed on the first contact layer, a plurality of second electrodes on the second contact layers, a first polymer layer that surrounds sidewalls of the plurality of stacks on the first contact layer, and a second polymer layer, which is transparent to infrared rays, to cover the second electrode on the second contact layer. A through hole corresponding to the plurality of stacks is formed in the substrate. |
