Claim:
1. An electrowetting display device comprising: a picture element comprising a first support plate, a second support plate and a space between the first support plate and the second support plate, the space comprising a first fluid and a second fluid immiscible with the first fluid, the second fluid being at least one of electroconductive or polar, the first support plate comprising: an electrode; a first layer having a first layer pattern, the first layer being at least one electronic component other than part or all of a transistor, the at least one electronic component in contact with the electrode for application of a potential to the electrode to apply an electric field extending between the electrode and the second fluid, a configuration of the first fluid and the second fluid depending on a magnitude of the electric field; and a second layer between the first layer and the space, the second layer having a second layer surface in adjoinment with at least one of the first fluid or the second fluid, the second layer surface having a shape which at least partly corresponds with the first layer pattern, and the second layer surface being stepped between a first part of the second layer surface and a second part of the second layer surface, a plane of the first part of the second layer surface substantially parallel to a plane of the second part of the second layer surface, the electrode located at least partly between the first layer and the second layer.
