Abstract
A directional liquid crystal display, capable of suppressing Moiré patterns, includes a liquid crystal display module; a backlight module with a small divergence angle, for emitting light toward the liquid crystal display module, wherein a full width at half maximum (FWHM) of light energy distribution of the backlight module is less than 50 degrees; and a light directivity module, disposed between the backlight module and the liquid crystal display module.
