Abstract

An optical structure is provided. The optical structure includes a first substrate, a second substrate, a sealant, a light-modulating layer and a first conductive layer. The second substrate is disposed opposite to the first substrate. The sealant is disposed between the first substrate and the second substrate. The sealant is disposed around to form a visible area. The light-modulating layer is disposed in the visible region between the first substrate and the second substrate. The first conductive layer has a plurality of strip structures. The plurality of strip structures are disposed in the visible area to form an effective area. The visible area partially overlaps the effective area.
