Patent ID: 7403253

Claim:
An in plane switching mode liquid crystal display device, comprising: a first substrate and a second substrate; a plurality of gate lines disposed horizontally on the first substrate; a plurality of data lines disposed vertically on the first substrate; a common line between the gate lines, the gate lines, the data lines and the common line defining a first to a fourth sub-pixels arranged in a 2×2 matrix form; a thin film transistor at an intersection of the gate lines and the data lines in each sub-pixel; at least one pair of a common electrode and a pixel electrode disposed in each of the sub-pixels, the pixel electrode at each sub-pixel being connected to the thin film transistor thereof; two first storage lines respectively connected to the pixel electrodes of the upper two sub-pixels of 2×2 matrix form and disposed on the gate line; two second storage lines respectively connected to the pixel electrodes of the lower two sub-pixels of 2×2 matrix form and disposed on the common line; and a liquid crystal layer formed between the first and the second substrates.
