Abstract
The present invention is directed to a highlight color display. One of the key features of the invention is the dark color of the display fluid filled in the microcups, which allows the dark state to appear black. There is no alignment required between the pixel electrodes and the microcups. In practice, a standard active matrix array may be used to drive the display device.
