A liquid crystal display (LCD) panel and an LCD device using the same are provided. The LCD panel includes a first and a second substrate, wherein a liquid crystal layer is sealed between the first and the second substrates. The first substrate has a plurality of pixel unit each including a data line, a scan line, a switch element, a first pixel electrode, a second pixel electrode, a first aligning electrode and a second aligning electrode. The scan line corresponds to a gap between the first pixel electrode and the second pixel electrode. The switch element has an input terminal, a control terminal, a first output terminal and a second output terminal. The first aligning electrode and the second aligning electrode correspond to the edges of the first pixel electrode and the second pixel electrode respectively, and receive a voltage of a common electrode.
