Claim:
1. An electrically controllable display element ( 1 ) for an optical display device, with a structured layer ( 2 ), that has plurality of spatially arranged pixels ( 3 ), each with a pixel volume ( 3 ) that stands in fluid communication with at least one reservoir ( 4 ) and with at least one electrode layer ( 6 ) directly or indirectly on a structured side ( 2 . 1 ) of the structured layer ( 2 ), as well as an active matrix ( 7 ) consisting of thin film transistors, which has selectively controllable control electrodes, in order to selectively apply an electric field to one or more specific pixels ( 3 ), so that between the pixel volume ( 3 ) and the associated reservoir ( 4 ) an electrical conducting and/or polar fluid ( 5 ) is movable back and forth, wherein the at least one electrode layer ( 6 ) extends in one piece over the structured side ( 2 . 1 ) of the structured layer ( 2 ) including spaces between adjacent pixels, and wherein the structured side ( 2 . 1 ) is arranged to face the active matrix ( 7 ).
