Abstract

This paper describes a micropatterning method of hemispherical dome shape photonic colloidal crystals (PCCs) in microchannels for a wide-viewing-angle optical color filter of a reflective display. We fabricated hemispherical dome-top PDMS microchannels and crystalized colloidal particles inside the microchannel. These dome-shape micorchannels enable us to observe reflected light (structural color) from the PCCs in wide-viewing-angle (Fig. 1). We succeeded in patterning of two types of hemispherical PCCs in the dome-top micorchannels, and confirmed that those patterned PCCs reflected their structural color in wide-viewing-angle. Our patterning method could be effective to realize an optical filter for full-color, wide-viewing-angle and low-energy-consumption reflective displays.
