Abstract
A display apparatus includes a plurality of electrofluidic chromatophore (EFC) pixel cells. Each pixel cell includes a fluid holder for holding a polar fluid and a non-polar fluid having differing display properties, the fluid holder including a reservoir having an orifice with a small visible area projected in the direction of a viewer onto the polar fluid, and a channel with a geometry having a large visible area projected in the direction of a viewer onto the polar fluid. The channel is connected to the reservoir via said orifice so as to enable free movement of the polar fluid and non-polar fluid between the channel and the reservoir. The reservoir is formed in a laminated resin structure of homogenous resin film layers, including an orifice film layer and a reservoir film layer.
