<p>PROBLEM TO BE SOLVED: To provide a device with excellent picture quality capable of driven by a low voltage and low power consumption by being satisfied dielectric anisotropy of a liquid crystal composition, the substantial thickness of the liquid crystal composition layer, the electrode width of a pixel electrode in the latitudinal direction, the electrode width of a counter electrode in the latitudinal direction and the interval between the pixel electrode and the counter electrode with specified relations. SOLUTION: Every pixel is arranged in a crossing area among a scan signal line GL, a counter voltage signal line CL and two pieces of adjacent video signal lines DL. Further, every pixel contains a thin film transistor TFT, a storage capacity Cs+g , the pixel electrode PX and the counter electrode CT. At this time, the dielectric anisotropyΔεof the liquid crystal composition, the substantial thickness deff of the liquid crystal composition, the electrode width Wp of the pixel electrode PX in the latitudinal direction, the electrode width Wc of the counter electrode CT in the latitudinal direction and the interval L between the pixel electrode PX and the counter electrode CT are satisfied withΔε>0, 2.8μm<deff <4.5μm, and 1.2×deff <Wp <L/1.2, 1.2×deff Wc <L/1.2.</p> |
