Abstract

An optical interference color display is provided. The optical interference color display comprises a color filtering substrate, a patterned support layer, a plurality of first electrodes, a plurality of optical films and a plurality of second electrodes. The patterned support layer and the first electrodes are positioned on the color filtering substrate with the patterned support layer between the first electrodes. The optical films are positioned on the first electrodes. The second electrodes is positioned over the first electrodes and supported through the patterned support layer such that an air gap with identical thickness is produce between every pair of second electrode and first electrode. Using the color filtering substrate to show color images, air gap between the first electrodes and the second electrodes are identical and hence simplifies the manufacturing process.
