A liquid crystal display (LCD) device, comprising:
- a. a first structure comprising:
- i. a first substrate having a first surface and an opposite, second surface defining a body portion therebetween;
- ii. a plurality of scanning lines regularly spaced and formed on the second surface of the first substrate along a first direction;
- iii. an insulation layer formed on the first substrate covering the plurality of scanning lines;
- iv. a plurality of signal lines regularly spaced and formed on the insulation layer crossing over the plurality of scanning lines along a second direction that is substantially perpendicular to the first direction;
- v. a passivation layer formed on the insulation layer covering the plurality of signal lines thereon;
- vi. a plurality of first common electrodes regularly spaced and formed on the passivation layer along the second direction;
- and
- vii. a plurality of pixel electrodes regularly spaced and formed on the passivation layer along the second direction, each of the pixel electrodes located between two neighboring first common electrodes;
- b. a second structure comprising:
- i. a second substrate having a first surface and an opposite, second surface defining a body portion therebetween;
- ii. a black matrix formed on the first surface of the second substrate directly facing the plurality of scanning lines and the plurality of signal lines in the first structure;
- iii. a color filter layer formed on the remaining portion of the second substrate;
- iv. an overcoat layer formed on the color filter layer and the black matrix;
- v. a plurality of second common electrodes regularly spaced and formed on the overcoat layer along the second direction, each of the plurality of second common electrodes directly facing a corresponding one of the plurality of first common electrodes on the first substrate;
- and
- vi. a plurality of floating electrodes regularly spaced and formed on the overcoat layer on the second substrate along the second direction, each of the plurality of floating electrodes directly facing a corresponding one of the plurality of pixel electrodes on the first substrate;
- wherein the first structure and the second structure are positioned relative to each other such that a cell gap is defined therebetween;
- c. a liquid crystal layer having a plurality of liquid crystal molecules, the liquid crystal layer being positioned in the cell gap between the first structure and the second structure;
- wherein each of the plurality of floating electrodes is electrically disconnected from the pixel electrodes, the first common electrodes, and the second common electrodes, such that, when a signal voltage is applied to a pixel electrode, the voltage is coupled to a corresponding floating electrode via the capacitance between the pixel electrode and the floating electrode, thereby inducing an electric field in the liquid crystal layer in the region between the pixel electrode, the floating electrode, the first common electrodes and the second common electrodes, and wherein the liquid crystal molecules in the region are rotated according to the electric field.
