Abstract: A liquid crystal display and a method for driving the same. The liquid crystal display includes: gate lines arranged in a row direction; data lines arranged in a column direction; and subpixels arranged in basic units of eight subpixels. Each subpixel is each connected to one of the gate lines and one of the data lines, and the subpixels are continuously arranged along a row and are arranged in a matrix. In the basic units, polarities between adjacent subpixels from a first subpixel to a fourth subpixel along the row are opposite to each other, polarities between adjacent subpixels from a fifth subpixel to an eighth subpixel along the row are opposite to each other, and polarities of the fourth subpixel and the fifth subpixel are the same.
