Abstract The present invention relates to liquid crystal displays, wherein the incident light and reflected light going through the display are not specularly related. The incident light can be at a range of angles to the display while the reflected light, i.e. the viewing direction is at or nearly normal to the display. Also disclose the new image-mode and shadow-mode nonspecular liquid crystal displays. Such displays have very bright background and are free from viewing glare common in most liquid crystal displays. The present invention applies to all twist angles, e.g. the 90 DEG TN, the 120 DEG and 150 DEG HTN, the 180 DEG , 240 DEG and 270 DEG STN displays.
