PURPOSE: A liquid crystal display device is provided to improve visibility by changing data according to the brightness of external light. CONSTITUTION: A liquid crystal display panel(100) includes a plurality of gate lines and a plurality of data lines and displays an image. A data driver(120) supplies a data voltage to a plurality of data lines. An external light sensor(150) generates a sensing signal by comparing the sensed brightness of the external light with a reference value. A data processing unit(140) changes input data according to the brightness of the external light and provides the changed data to the data driver. |
