Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.
