ABSTRACT
Color perception is an important part of our daily life and is normally achieved by incorporating colored pigments or dyes into objects or display devices. These pigments elements produce colors because they absorb a certain band of visible light. In the context of display devices, chemical pigments are widely used as color filters in liquid crystal displays (LCDs). This chapter discusses the design of plasmonic metal-insulator-metal (MIM) nanoresonators capable of spectrum filtering for various colors across the entire visible band. High resolution, slim dimension, and better power management are the final goals for the development of visual display technologies. Moving toward commercialization, two aspects should be focused on: first, further improvement of their optical performances, that is, transmission efficiency, color purity, and the incident angle independency, and second, development of a more efficient, high-throughput nanofabrication method to realize mass production with low costs.
