Abstract
RGB directive color reflectors with different directive angles were prepared and
assembled into reflective color LCD panels with a single polarizer. A moving
image with directive color reflection was successfully demonstrated using a TFT
drive. It was revealed that brightness was enhanced by gain reflection, contrast
was improved by off-axis reflection, and color gamut was expanded by holographic
color reflection within a directive angle corresponding to half of a viewing
angle.
