Abstract
A display system is built up of at least one display cell including an assembly containing a set of substrates at least one of which is transparent, a wall portion for supporting the set of substrates in opposition to one another defining a liquid confining space, a 1st-A electrode and a 1st-B electrode located on the side of the substrate facing the liquid confining space in a mutually electrically independent way, an insulating layer for covering the 1st-A electrode and the 1st-B electrode, an intermediate partition located at a boundary site between the 1st-A electrode and the 1st-B electrode and the second electrode located on the side of another substrate facing the liquid confining space, such that θ1 <θ2 <θ3, where θ1, θ2 and θ3 relate to hydrophilicity of the exposed wall portion, hydrophilicity of the intermediate partition, and hydrophilicity of the insulating layer.
