A transreflective liquid crystal display (LCD) apparatus with a single cell gap is presented, along with a method of driving the apparatus. The apparatus operates with low power consumption because its electro-optical characteristics in a transmissive region and a reflective region are equalized. The transreflective LCD apparatus includes first and second liquid crystal cells formed respectively in transmissive and reflective regions of a first subpixel, first and second thin film transistors connected respectively to the first and second liquid crystal cells, and first and second storage capacitors connected respectively to the first and second liquid crystal cells.
