Abstract:
1. An in-plane switching mode liquid crystal display device comprising: first and second substrates; a plurality of gate and data bus lines defining pixel regions and arranged on the first substrate; a common line in the pixel region, the common line and the data bus lines having a crossing relationship; a pair of first and second electrodes parallel to each other applying plane electric fields in the pixel regions; and a liquid crystal layer between the first and second substrates; wherein dΔn is in the range of 0.29-0.36 μm and transmittance is greater than or equal to 60 percent, where d is the thickness of the liquid crystal layer, and Δn is the refractive anisotropy of the liquid crystal molecule; a plurality of thin film transistors adjacent respective cross points of the gate and data bus lines, each of the thin film transistors including a gate electrode, a gate insulator, a semiconductor layer, and source and drain electrodes; a passivation layer on the thin film transistors; a first alignment layer on the passivation layer; a black matrix for preventing light from leaking around the TFTs gate bus line and data bus line; a color filter layer on the second substrate; and a second alignment layer on the color filter layer, wherein the first and second alignment layers comprises polysiloxanecinnamate; and wherein dΔn is selected to achieve a desired light transmittance and color-shift.
