Abstract

An electrowetting display device comprises a picture element having a first support plate and a second support plate having a space therebetween having a first fluid and a second fluid immiscible with the first fluid. The first support plate comprises a display area, adjoining the space, within which the first fluid is confined and having a first surface adjoining the space. A wall protrudes from the first support plate and is formed outside the display area along a part of the perimeter of the display area. The wall has a second surface facing the display area and adjoining the space. An electrode has a first portion adjacent to the first surface and a second portion adjacent to at least a part of the second surface such that a surface of the second portion including a long side of a cross section of the second portion faces the display area.

Description

technical field [0001] The invention relates to an electrowetting display device comprising a picture element. Background technique [0002] Electrowetting display devices comprising two support plates are known. One of these support plates comprises a pattern of walls defining picture elements of the display device. The area between the walls of the picture elements is called the display area, on which the display effect occurs. [0003] The space between the support plates contains a first fluid and a second fluid that are immiscible with each other. The configuration of the walls confines the first fluid within the display area. Electrodes are provided in the support plate within the display area. The first fluid causes a layer to form on the display area when no voltage is provided between the electrodes and the second fluid. Application of the voltage changes the configuration of the first fluid and the second fluid to provide a display effect. [0004] A problem ...
