Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel including a plurality of gate lines 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 said field data to said data lines, wherein the data driver is configured to apply a first constant voltage to said data lines in a last field out of said plurality of fields for said frame data in a range from a minimum gradation value to a first gradation value, and apply a voltage in accordance with said frame data in fields other than said last field for said frame data in the range from the minimum gradation value to the first gradation value, and the data driver is configured to apply a second constant voltage larger than said first constant voltage to said data lines in a top field out of said plurality of fields for said frame data in a range from a second gradation value to a maximum gradation value, wherein the first gradation value is less than the second gradation value, and apply a voltage in accordance with said frame data in fields other than the top field out of said plurality of fields for said frame data in the range from the second gradation value to the maximum gradation value.
