Abstract

A liquid crystal display aimed at improving response speed, movie characteristics and viewing angle dependence of gradation is provided as having a liquid crystal panel including a plurality of gate lined selecting pixels and a plurality of data lines supplying pixel data, and a data driver dividing one frame into a plurality of fields to thereby convert a frame data into a field data, and supplying the field data to the data line, wherein in the last field out of the plurality of fields, the data line is applied with a first constant voltage, for the frame data ranging from the minimum gradation value to a first gradation value, and in the top field out of the plurality of fields, the data line is applied with a second constant voltage larger than the first constant voltage, for the frame data ranging from a second gradation value to the maximum gradation value.
