A liquid crystal display device includes a first substrate, a gate line and a first data line disposed on the first substrate and insulated from each other, a first thin film transistor connected to the gate line and the first data line, a lower pixel electrode connected to the first thin film transistor, an interlayer insulating layer disposed on the lower pixel electrode, an upper pixel electrode disposed on the interlayer insulating layer and connected to the first thin film transistor and the lower pixel electrode, a second substrate facing the first substrate, a common electrode disposed on the second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The upper pixel electrode includes a plurality of minute branches. A ratio of an interval between the minute branches with respect to a thickness of the liquid crystal layer is 2.7 to 5.0.
