Yet,, do not have electrode on the color membrane substrates owing to be on array base palte, to form two-layer electrode pair liquid crystal to drive for the liquid crystal indicator of FFS mode; Therefore; Be easy to generate electrostatic charging, make the orientation disorder of liquid crystal, so can't enjoy high-quality demonstration.And, in case because electrostatic charging can't be easy to removal.

Existing solution is to do guarded electrode at the color membrane substrates outside surface, and guarded electrode is applied certain current potential.But the preparation guarded electrode need increase several procedures; To carrying out the film formation process of guarded electrode behind the substrate attenuation behind the one-tenth box; The assembling panel is later with the conducting operation of guarded electrode and array base palte public electrode etc.; As shown in Figure 1, guarded electrode 1 is formed at the outside surface of substrate 3, through conductive silver glue 2 public electrode of guarded electrode 1 with array base palte 4 is linked together.Guarded electrode 1 exposes outside in addition, receives the influence of extraneous factor big, therefore will produce unacceptable product, causes very big loss.

The utility model content

The technical matters that the utility model will solve provides a kind of color membrane substrates and display panels, can effectively prevent the generation of static, and improves the yield of product.

For solving the problems of the technologies described above, this practicality new embodiment provide a kind of color membrane substrates, comprising: substrate, guarded electrode, black matrix, color rete and planarization layer; Said guarded electrode is arranged at the medial surface of said substrate; Said black arranged in matrix is in the non-tight glue zone of said guarded electrode below; Said color rete is arranged at the medial surface of said substrate not by said black matrix and said guarded electrode region covered; Said planarization layer is arranged at the below of said color rete and said black matrix, and covers said black matrix and said color rete.

Wherein, said guarded electrode has identical figure with said black matrix.

Wherein, the material of said guarded electrode is tin indium oxide or zinc-tin oxide.

Wherein, said black matrix is the black matrix that is formed by resin material.

Wherein, but said planarization layer is the planarization layer that the negativity resin material by sensitization forms.

The embodiment of the utility model also provides a kind of display panels, comprising: color membrane substrates, and said color membrane substrates to the array base palte of box and be filled in said color membrane substrates and said array base palte between liquid crystal; Wherein, said color membrane substrates is aforesaid color membrane substrates, and said guarded electrode is connected with the public electrode of said array base palte.

Further, said guarded electrode is connected with the public electrode of said array base palte through the conductive gold spacer in the fluid sealant zone.

The beneficial effect of the technique scheme of the utility model is following:

In the such scheme; Inboard at color membrane substrates prepares guarded electrode, and guarded electrode is identical with black matrix figure, and the back links together the public electrode on guarded electrode and the array base palte through the conductive gold spacer in the fluid sealant; So can effectively prevent the generation of static, and improve the yield of product.

Embodiment

For technical matters, technical scheme and advantage that the utility model will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.

As shown in Figure 2, the embodiment of the utility model provides a kind of color membrane substrates, comprising: substrate 3, guarded electrode 1 (transparent conductive film is like tin indium oxide ITO or zinc-tin oxide IZO), black matrix 5, color rete 6 and planarization layer 7; Said guarded electrode 1 is arranged at the medial surface of said substrate 3; Said black matrix 5 is arranged at the non-tight glue zone of said guarded electrode 1 below as mask layer; Said color rete 6 is arranged at the medial surface of said substrate 3 not by said black matrix 5 and said guarded electrode 1 region covered; Said planarization layer 7 is arranged at the below of said color rete 6 and said black matrix 5, and covers said black matrix 5 and said color rete 6.

Wherein, said guarded electrode 1 and said black matrix 5 have identical figure, and said guarded electrode figure can be ignored the interference of box internal electric field.

Wherein, said guarded electrode 1 can be connected with the public electrode of array base palte 4 through the conductive gold spacer 9 in 8 li in fluid sealant zone; Wherein said array base palte 4 is and the array base palte of said color membrane substrates to box.

Wherein, said black matrix 5 can be the black matrix that is formed by resin material.

Wherein, but said planarization layer 7 can be the planarization layer that the negativity resin material by sensitization forms.

The foregoing description of the utility model prepares guarded electrode 1 in the inboard of color membrane substrates; Receive the influence of extraneous factor little, and improve the yield of product, guarded electrode 1 is identical with black matrix 5 figures; The back links together the public electrode on guarded electrode 1 and the array base palte 4 through the conductive gold spacer 9 in 8 li in fluid sealant zone; Said guarded electrode 1 has identical current potential with public electrode, promptly is equivalent to ground connection, when the CF side has external interference (like static); Because the shielding action of guarded electrode can effectively prevent the influence of external electrical field to the box internal electric field.
