Through connection of a display device

A first support plate for an electrowetting display device comprising at least one picture element having a display area, the first support plate comprising a first electrical element, a second electrical element and a through-connection electrically connecting the first electrical element to the second electrical element, wherein the through-connection is arranged such that when the first support plate is assembled in the electrowetting display device and the display area is projected through the first support plate the through-connection is outside the projected display area.

A method of manufacturing a first support plate for an electrowetting display device having at least one picture element, the first support plate, a second support plate and a space between the first support plate and the second support plate, the space including a first fluid and a second fluid immiscible with each other, the first support plate including a first electrical element, a second electrical element and a through-connection electrically connecting the first electrical element to the second electrical element, the at least one picture element including at least part of the second electrical element and a display area, the through-connection being arranged such that, when the display area is projected through the first support plate, the through-connection is outside the projected display area,

• the method comprising:
• forming the first electrical element from electrically conductive material;
• forming at least one layer on the first electrical element, forming the second electrical element from electrically conductive material on said at least one layer, including forming the through-connection through the at least one layer.
