Abstract
A liquid crystal display device includes a first substrate including an electrode structure layer defining a pixel and a switching device configured to switch the pixel, an opposite second substrate facing the first substrate and including a common electrode, and a liquid crystal layer disposed between the first and second substrates. The electrode structure layer includes a coupling electrode, a first pixel electrode, a second pixel electrode, and an insulating layer disposed between the coupling electrode and the second pixel electrode. An absolute value difference between a first product RpCp of a resistance Rp and a capacitance Cp defined by the coupling electrode, the insulating layer, and the second pixel electrode, and a second product R2C2 of a resistance R2 and a capacitance C2 defined by the second pixel electrode, the liquid crystal layer, and the common electrode is less than or equal to 10.
