An LCD apparatus includes first and second substrates, and a liquid crystal layer. The first substrate includes a main region having switching device and first electrodes, and a sub region having a second electrode. The switching device applies a data signal to the first electrodes in response to a gate signal applied to the second electrodes. The sub region is disposed at a circumference of the main region. The second substrate includes a third electrode that faces the first and second electrodes. A reference signal that has a different magnitude from the gate signal is applied to the third electrode. The liquid crystal layer is interposed between the first and second substrates. According to an embodiment of the present invention, a bright line surrounds main region through which images are displayed. Thus, the bright line brings out the images. That is, the images are better defined.
