Method for producing a display element for an electro-wetting display and a display element for an electro-wetting display

A method for producing a display element for an electrowetting display with the steps:

• a) providing a display chamber with a first volume, the bottom of which is formed by a first intermediate film which has a first opening, whereby the display chamber is closed by an at least partly transparent cover which is at some distance from the first intermediate film;
• b) providing a reservoir chamber for fluid with a second volume, the bottom of which is formed by a substrate and which has a second intermediate film at some distance from it which closes the reservoir chamber and has a second opening;
• c) providing a quantity of fluid which is greater than both the first volume as well as the second volume but is less than the sum of the first volume and second volume;
• d) dividing the quantity of fluid into a first partial drop and a second partial drop;
• e) introducing the first partial drop into the display chamber;
• f) introducing the second partial drop into the reservoir chamber;
• g) bringing together the display chamber and the reservoir chamber so that the first opening and the second opening at least partly overlap;
• and
• h) applying an electrical field to the display chamber and to the reservoir chamber, thereby uniting the first partial drop and the second partial drop.
