Abstract
A switchable optical device is provided having a first substrate (11), a second substrate (12) and a seal (114). The two substrates (11, 12) and the seal (114) are arranged such that a cell having a cell gap is formed and a switchable medium (10) is located inside the cell gap. The first substrate (11) has a first transparent electrode (21) and the second substrate (12) has a second transparent electrode (22). The electrodes (21, 22) are facing towards the cell gap. The two substrates (11, 12) are arranged such that the first substrate (11) has a first region (71) adjacent to a first edge (41) of the first substrate (11) which does not overlap with the second substrate (12) and the second substrate (12) has a second region (72) which does not overlap with the first substrate (11). A first electrically conducting busbar (31) is arranged in the first region (71) and a second electrically conducting busbar (32) is arranged in the second region (72). A first terminal is electrically connected to the first busbar (31) and a second terminal is electrically connected to the second busbar (32). The first substrate (11) and the second substrate (12) each have an edge deletion (116) in which…
