摘要： Provided are a liquid crystal display (LCD) device and a driving method thereof for displaying high-resolution images. The LCD device comprises a plurality of pixel groups including a first pixel and a second pixel arranged in a same pixel column of two adjacent pixel rows. Each of the first and second pixels forms a dot in combination with an adjacent pixel disposed at each side of the first and second pixels in a corresponding pixel row. A plurality of gate lines arranged for each pixel row in a horizontal direction to transfer a gate voltage to the respective pixels. A plurality of data lines formed in a vertical direction while traversing the gate lines and arranged for each pixel column to transfer a data voltage to the respective pixels. A switching device is formed in each pixel which has a first side and a second side. The switching devices formed at pixels of a first pixel group row are connected to the data lines on the first side, and switching devices formed at pixels of a second pixel group row are connected to the data lines of the second side.
