Abstract
The invention discloses a liquid crystal display device. The device comprises a color film substrate provided with a first indium tin oxide (ITO) layer, and an array substrate provided with a second ITO layer and a common electrode, wherein the array substrate and the color film substrate are arranged oppositely; a contact hole is formed in the array substrate corresponding to the common electrode; a columnar spacer is arranged on the color film substrate corresponding to the common electrode; and the first ITO layer coats the columnar spacer and is contacted with the second ITO layer on the common electrode. The liquid crystal display device can effectively increase the voltage of the common electrode and reduces flicker and crosstalk of a panel.
Description
Technical field
The present invention relates to a kind of display device, particularly a kind of liquid crystal indicator.
Background technology
Common liquid crystal indicator; As shown in Figure 1; Its panel driving is from frame glue 30, to add the conducting particles (not shown); By the public electrode (CS electrode) 23 of array base palte 20 ITO (Indium Tin Oxides, the indium tin oxide) layer 11 of public electrode voltages to the color membrane substrates 10 is provided, makes the liquid crystal (not shown) experience the electric field that forms between the pixel electrode voltage on public electrode voltages and the array base palte 20 and drive; But normal because public electrode voltages not enough, cause that panel has flicker, demonstration such as crosstalk is bad.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned existing existence the purpose of this invention is to provide a kind of increase public electrode voltages, the liquid crystal indicator of reduce panel flash, crosstalking.
Technical scheme: for realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of liquid crystal indicator, comprising:
One is provided with the color membrane substrates of an ITO layer;
One is provided with the array base palte of the 2nd ITO layer and public electrode, and this array base palte and said color membrane substrates are oppositely arranged;
Position with respect to public electrode in said array base palte is provided with contact hole; Said color membrane substrates is provided with column spacer with respect to the position of said public electrode, and a said ITO layer coats this column spacer and contacts with the 2nd ITO layer on the said public electrode.
Beneficial effect: the present invention increases the size and the homogeneity of public electrode voltages through making an ITO layer and a common electrode contact that coats column spacer, and effectively reduce flicker of display panel, crosstalk etc. shows bad, improves the display quality of liquid crystal indicator.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment 1:
As shown in Figure 2; Be provided with black-matrix layer 12, chromatograph 13 and an ITO layer 11 successively in color membrane substrates 10 sides; On array base palte 20 sides, be provided with public electrode 23 successively, principal ingredient is the insulation course 22 and the 2nd ITO layer 21 of silicon nitride (SiNx), a contact hole is dug at array base palte 20 corresponding public electrodes 23 places, and the part of the 2nd ITO layer 21 is located immediately on the public electrode 23; Color membrane substrates 10 relative public electrodes 23 places make the convexity 41 that is formed by the colour layer material stack; This convexity is as the column spacer of 20 of color membrane substrates 10 and array base paltes, and an ITO layer 11 coats should convexity and contact with the 2nd ITO layer 21, thereby makes an ITO layer 11 and public electrode 23 conductings; Can effectively increase the size and the homogeneity of public electrode voltages, reduce flicker of display panel, crosstalk etc. shows bad.The ITO layer that is located immediately in the contact hole on the public electrode 23 breaks off with the ITO layer that is located on the insulation course; And the ITO layer material that is located on the insulation course is used for making pixel electrode, can avoid the ITO layer on protruding 41 to contact and short circuit with pixel electrode on the array base palte.The column spacer of present embodiment is produced on the non-display area of display panels; Certainly, also can be formed at the viewing area.
Embodiment 2:
As shown in Figure 3; The difference of present embodiment and embodiment 1 is: also be provided with dielectric materials layer 42 on protruding 41; As the column spacer of 20 of color membrane substrates 10 and array base paltes, an ITO layer 11 coats and should convexity contact with dielectric materials layer and with the 2nd ITO layer 21 jointly for this convexity and dielectric materials layer, thereby makes an ITO layer 11 and public electrode 23 conductings; Can effectively increase the size and the homogeneity of public electrode voltages, reduce flicker of display panel, crosstalk etc. shows bad.The column spacer of present embodiment is produced on the viewing area of display panels; Certainly, also can be formed at non-display area.
Embodiment 3:
As shown in Figure 4; The difference of present embodiment and embodiment 1 is: column spacer is made by other photoresist layer 43; The one ITO layer 11 coats this photoresist layer and contacts with the 2nd ITO layer 21; Thereby make an ITO layer 11 and public electrode 23 conductings, can effectively increase the size and the homogeneity of public electrode voltages, reduce flicker of display panel, crosstalk etc. shows bad.In addition; The alignment film 50 that Fig. 4 also shows on the ITO layer (also has alignment film among embodiment 1 and the embodiment 2; Just not shown in Fig. 2 and Fig. 3); This alignment film stops an ITO layer 11 and public electrode 23 conductings, but alignment film 50 is not to cover the ITO layer fully, so public electrode 23 is avoided the position of alignment film 50; Certainly, also can avoid,, still can be when an ITO layer 11 contacts with the 2nd ITO layer 21 break because of alignment film density unevenness or pressurized because the thickness of alignment film as thin as a wafer.The column spacer of present embodiment is produced on the viewing area of display panels; Certainly, also can be formed at non-display area.
