A liquid crystal display (LCD) device and an LCD panel are disclosed. The LCD panel comprises charging scanning lines, discharging scanning lines, first data lines, second data lines and pixel units. The charging scanning lines and the discharging scanning lines are arranged alternately and parallel with each other in a first direction. The first data lines and the second data lines are arranged parallel with each other in a second direction and insulatedly intersect the charging scanning lines and the discharging scanning lines. Each pixel unit comprises a charging TFT, a discharging TFT and a pixel electrode. When two adjacent charging scanning lines are being scanned in the LCD panel, two adjacent discharging scanning lines located in other rows different from those of the two adjacent charging scanning lines being scanned are scanned within a same scanning time frame. The LCD panel can extend the charging time of gates.
