Abstract
A liquid crystal display device includes an array substrate provided with pixel electrodes and a counter electrode provided opposite to the array substrate, and a liquid crystal layer held between the array and counter substrates. The liquid crystal layer, and the array and counter electrode define a liquid crystal capacitor. The array substrate disposed on an insulation substrate includes a plurality of signal and scanning lines crossing each other. A thin film transistor is provided in the vicinity of each crossing point. The thin film transistor is connected to the pixel electrode. A storage capacitance is defined between the pixel electrode and a storage capacitance line. A parasitic capacitance is further defined between the pixel electrode and the signal line. The parasitic capacitance is 4% or less of an entire pixel capacitance including the liquid crystal, storage and parasitic capacitance in order to avoid crosstalk between the pixels.
