Removed picture & caption to lens with a "viewing angle", confused from "angle of view". |

Line 7:
The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen. Some display devices exhibit different behaviour in horizontal and vertical axis, requiring users and manufacturers to specify maximum usable viewing angles in both directions. Usually the screens are aligned and used to facilitate greater viewing angle in horizontal level, and smaller angle in the vertical level, should the two of them be different in magnitude.
Early [[LCD]]s had strikingly narrow [[viewing cone]]s, a situation that has been improved with current technology.
