ABSTRACT:
A paper-white reflective display that has improved photopic white reflectance, a high contrast, a lack of haze or opaqueness when viewed from various viewing angles and lower drive voltages. The paper-white reflective display includes first and second substrates, a plurality of groups of liquid crystal and polymer layers located between the first and second substrates, each of the plurality of groups of liquid crystal and polymer layers being reflective of different wavelengths of light and a voltage source connected between the first and second substrates that selectively applies a voltage to all of the liquid crystal and polymer layers.
