PURPOSE: A liquid crystal display is provided to prevent the deterioration of image quality in data pattern by preventing polarity deflection of liquid crystal cells. CONSTITUTION: An LCD panel has data lines, gate lines, TFTs, and liquid crystal cells. TFTs are formed at the intersection of the data lines and the gate lines. A data driving circuit converts digital video data into positive polarity / negative data voltages. A data driving circuit makes the polarity of data voltages reverse. The data voltages are supplied to the data lines. The gate driving circuit supplies a scan signal to the gate lines.
