Abstract
A reflective type color liquid crystal device includes first and second substrates. Each substrate has an opposing inner surface. Each of the opposing inner surfaces has an electrode and forms a matrix-patterned dot group. Multiple liquid crystals are disposed between the substrates. The device also includes multiple color filters, including at least two different colors, at least one polarizing plate, and a reflective plate. At least one color of the color filters has a transmissivity of at least 50% for light of all the wavelengths in a range between 450 nm and 660 nm.
