Claim Text:
1. A liquid crystal device comprising: an element substrate which has a plurality of scan lines and a plurality of data lines, and has a pixel electrode and a switching element provided to correspond to an intersection point between the scan line and the data line; a counter substrate which is disposed to be opposed to the element substrate and has a counter electrode; a liquid crystal layer which is sandwiched between the element substrate and the counter substrate; a first alignment film which is provided on a side of the element substrate close to the liquid crystal layer; a second alignment film which is provided on a side of the counter substrate close to the liquid crystal layer; a first dielectric film which is provided between the pixel electrode and the first alignment film, has a film thickness less than that of the liquid crystal layer, has a specific resistance higher than that of the liquid crystal layer, and is made of SiO a second dielectric film which is provided between the counter electrode and the second alignment film, has a film thickness less than that of the first dielectric film, has a specific resistance higher than that of the liquid crystal layer, and is made of SiO wherein a counter electrode potential, which is set to reduce flicker caused by a parasitic capacitance of the switching element, is applied to the counter electrode, wherein a positive voltage and a negative voltage are alternately applied to the pixel electrode when the positive voltage is a high-potential voltage and the negative voltage is a low-potential voltage relative to the counter electrode potential as a reference, and wherein in predetermined durations such as a first duration during which the positive voltage is applied and a second duration during which the negative voltage is applied, the length of the first duration is set to be longer than the length of the second duration.
