Abstract

Multilayer film (1) with electrically switchable optical properties, comprising, arranged sheet-wise in order, at least: —a first carrier film (5), —a first electrically conductive layer (3), —an active layer (2), —a second electrically conductive layer (4) and—a second carrier film (6), wherein—the multilayer film (1) has at least two circumferential separating lines (16), which separate an insulated edge region (18) from the first electrically conductive layer (3) and the second electrically conductive layer (4), —the first carrier film (5) and the second carrier film (6) are welded in at least a part of the insulated edge region (18) to form a sealed region (7), and—the separating lines (16) have a width of 10 μm to 500 μm.
