Abstract
A liquid crystal display (LCD) device includes a first substrate, gate lines formed on the first substrate, data lines perpendicularly crossing the gate lines to define red, green, and blue (R/G/B) sub-pixels, thin film transistors (TFTs) disposed at each intersection where the gate lines cross the data lines, common lines disposed in parallel with the gate lines, the common lines including a common line capacitance (Cdc) control portion, pixel electrodes insulated from the common lines and connected to the TFTs, a second substrate opposite to the first substrate and bonded to the first substrate, and a liquid crystal layer disposed between the first and second substrates.
