Liquid crystal display device and method of driving the same

A method of driving a liquid crystal display device having a display portion including a first substrate, a second substrate opposing to the first substrate, a liquid crystal layer held between the first and second substrates, and a plurality of pixels arranged in a delta shape;

• the first substrate including, a plurality of pixel electrodes respectively arranged in the pixels, scanning lines extending in a first direction, signal lines extending in a second direction crossing orthogonally with the first direction, and pixel switches arranged around a crossing area of the scanning lines and the signal lines, corresponding to respective pixel electrodes, the method comprising the steps of:
• forming the signal lines extending in a space between the pixel electrodes in a meandering shape in a second direction, and two kinds of color pixels connected with a common signal line by turn via the pixel switch,
• turning on the pixel switch by the scanning line sequentially driven under control of a scanning line driving circuit,
