Liquid crystal display device

摘要

A liquid crystal display device includes a substrate, a gate line, first and second data lines, a first power line, first, second, third and fourth switching elements, and first, second, third and fourth pixel electrodes. The first switching element is connected to the gate line and the first data line. The second switching element is connected to the gate line and the first power line. The third switching element is connected to the gate line and the second data line. The fourth switching element is connected to the gate line and the first power line. The first to fourth pixel electrodes are connected to the first to fourth switching elements, respectively. Thus, a light leakage may be prevented and an aperture ratio of a display substrate may be enhanced.
