1. A display device, comprising:
a liquid crystal display panel, comprising:
a pixel matrix, composed of more than two sub-pixels, wherein the colors of three adjacent sub-pixels located in the same row are different, and the colors of all sub-pixels located in the same column are the same;
two or more data lines parallel to each other, each data line is located between two adjacent columns of sub-pixels; and
two or more scan lines parallel to each other, each scan line is located between two adjacent rows of sub-pixels;
wherein each data line is connected to at least one pixel group successively, each pixel group comprises three sub-pixels with different colors, which are respectively located on two sides of the data line, and in the pixel group, each data line is connected to three sub-pixels in sequence;
a first driving unit, electrically connected to the data lines and inputs grayscale voltages to a plurality of the data lines;
a second driving unit, electrically connected to the scan lines and inputs scan signals to a plurality of the scan lines; and
a backlight module, comprising a light-emitting surface, wherein the liquid crystal display panel is disposed on the light-emitting surface of the backlight module,
wherein when the first driving unit inputs the grayscale voltages to the data line, the polarities of the grayscale voltages of the pixel groups connected to the data line are the same, and the polarities of the grayscale voltages of the pixel groups connected to the data lines on both sides of the data line are opposite to the polarities of the grayscale voltages of the pixel groups connected to the data line,
wherein when the first driving unit inputs a positive grayscale voltage to the data line, the pixel group connected to the data line is in a bright state.
