A pixel structure and a liquid crystal display device are disclosed. The pixel structure is formed on a substrate. The substrate includes at least two scan lines and at least one data line formed thereon. The pixel structure includes a main pixel, a first subpixel, and a second subpixel. The main pixel is electrically coupled to one of the two scan lines and the data line. The first subpixel is electrically coupled to the two scan lines and the data line. The second subpixel is electrically coupled to the two scan lines and the first subpixel. The present invention is capable of solving the color shift problem without a high frequency driving method and a large number of scan lines.
