Abstract
To produce a display element for an electrowetting display, there is provided a quantity of fluid which is greater than both the first volume of a display chamber and the second volume of a reservoir chamber, but less than the sum of the first volume and second volume. The fluid is divided into first and second partial drops, the first being introduced into the display chamber, the second being introduced into the reservoir chamber. The display and reservoir chambers are brought together so that a first opening in a first intermediate film of the display chamber and a second opening in a second intermediate film of the reservoir chamber at least partly overlap. An electrical field is applied to the display chamber and to the reservoir chamber, thereby uniting the first partial drop and the second partial drop.
