In a liquid crystal device according to the invention, a pre-tilt angle of a liquid crystal layer is greater on an opposing electrode side than on a pixel electrode side. A high potential and a low potential relative to an opposing electrode potential are alternately applied to pixel electrodes through switching elements; and the opposing electrode potential is higher than a standard potential, the standard potential being a potential in which the average potential between the high potential and the low potential has been shifted by an amount equivalent to the average value of the amount of change in the potential of the pixel electrodes caused by parasitic capacitance in the switching elements when the high potential is applied to the pixel electrodes and the amount of change in the potential of the pixel electrodes caused by parasitic capacitance when the low potential is applied to the pixel electrodes.

A liquid crystal display device includes a device substrate that includes a pixel electrode, a counter substrate that is formed opposite the device substrate and that includes a counter electrode, a liquid crystal layer that is formed between the device substrate and the counter substrate, a first alignment layer that is formed on a side of the device substrate which is closer to the liquid crystal layer, and a second alignment layer that is formed on a side of the counter substrate which is closer to the liquid crystal layer. The pixel electrode is made of a material having a work function smaller than that of a material for the counter electrode. The first alignment layer has substantially the same density as that of the second alignment layer, and the thickness dof the first alignment layer is greater than the thickness dof the second alignment layer.
