Preferably, this liquid crystal material is the liquid crystal material (be called for short negative liquid crystal material) of negative dielectric anisotropic, and promptly the specific inductive capacity of its molecular long axis direction is less than the specific inductive capacity of short-axis direction, so it can be arranged with the direction perpendicular to direction of an electric field in electric field.Select for use the negative liquid crystal material that liquid crystal material molecules 6 is reversed in electric field to arranging perpendicular to the direction of array base palte 11 on the edge.Certainly,, and cooperate different chiral additiveses, liquid crystal material molecules 6 is reversed by required direction if use the positivity liquid crystal material.
On array base palte 11, be provided with the array of pixel drive unit, wherein the liquid crystal material molecules 6 that can be used in the driving liquid crystal panel pixels of pixel drive unit is reversed.Wherein, array base palte 11 is provided with the gate line and the source electrode line of latticed arrangement, at each infall formation thin film transistor (TFT) of gate line and source electrode line, and pixel drive unit of the corresponding formation in each thin film transistor (TFT) place.Because the structure of gate line, source electrode line, thin film transistor (TFT) etc. is known, so be not described in detail at this.
In each pixel drive unit; Include pixel electrode 3 and public electrode 4; Wherein pixel electrode 3 links to each other with the drain electrode of thin film transistor (TFT); And public electrode 4 links to each other with public electrode wire, and when pixel electrode 3 and public electrode 4 were all charged, they can produce the electric field that is parallel to array base palte 11 in liquid crystal material.
Concrete, public electrode 4 is a tabular, which is provided with dielectric layer 5; And pixel electrode 3 comprises a plurality of parallel and pixel electrode bars 3 that be provided with at interval, and these pixel electrode bars 3 are positioned on the public electrode 4, and separates (promptly realizing mutually insulated) through dielectric layer 5 and public electrode 4.Obviously, though the dielectric layer 5 among Fig. 1 and Fig. 2 is complete layers,, also be feasible if only dielectric layer 5 is set at the lower position of pixel electrode bar 3.
In above-mentioned pixel drive unit; The exposed portions serve of the public electrode 4 of each pixel electrode bar 3 and its both sides all can produce electric field between (referring to not by the part of the public electrode 4 of pixel electrode 3 coverings); Therefore its interelectrode distance that produces electric field is shorter; Thereby can make electric field intensity higher, and make the electric field at liquid crystal material diverse location place more even, and the parallel electric field of generation that can be as much as possible and array base palte 11.Certainly, pixel electrode 3 also can with public electrode 4 parts under it between produce vertical electric field, but this electric field does not exert an influence to procedure for displaying.
Preferably, this public electrode 4 is processed by tin indium oxide (ITO) material with pixel electrode 3.Because the tin indium oxide material is transparent,, can improve the transmitance of display panels so can not impact to seeing through of light by its electrode of processing.
