摘要： A liquid crystal display includes a scanning voltage driver which applies selective scanning voltages to scanning electrodes of a liquid crystal display panel one group of M (an integer of 2 or greater) adjacent scanning electrodes at a time in accordance with M orthogonal function data. A data voltage driver applies to data electrodes of the liquid crystal display panel data voltages selected from M+1 data voltages in accordance with a coincidence number representing a number of coincidences between values of M display data corresponding to the M adjacent scanning electrodes in a current group of scanning electrodes and values of the M orthogonal function data corresponding to the M adjacent scanning electrodes in the current group. The data voltage driver controls a correction period in accordance with a value of a difference between (1) a coincidence number corresponding to the current group of scanning electrodes and (2) a coincidence number corresponding to a previous group of scanning electrodes, and applies to the data electrode during the correction period a corrected data voltage which is equal to a sum of a correction voltage and one of the M+1 data voltages.

摘要： A light control element capable of controlling deflection of light output through a light guide plate to a desired output viewing angle is provided. A light control element (prism sheet) has a plane of incidence on one surface thereof, and a plane of output on the other surface thereof. The plane of incidence is formed as having thereon a number of prism portions arrayed in parallel. Each of the prism portions has a first prism surface allowing incidence of light, and a second prism surface where the light entering through the first prism surface is reflected by total reflection on the inner side. The second prism surface has an outwardly-swelled curved profile, formed with a curvature that allows the light to output through the plane of output at a second output viewing angle wider than a first output viewing angle of a case where the second prism surface is flat.
