Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a liquid crystal display device, and more particularly to an in-plane switching liquid crystal display device. [Prior Art] The liquid crystal in the panel of the liquid crystal display device itself has no illuminating property, and the electric field is used to control the twist of the liquid crystal molecules to achieve the passage or non-pass of light, thereby achieving the purpose of display. In a conventional liquid crystal display device, electrodes are formed on the surface of two glass substrates to form an electric field for controlling the twist of the liquid crystal molecules. The electrodes are made of a transparent material, and the electrodes of the two bottom electrodes are oppositely disposed to form an electric field perpendicular to the surface of the substrate. Since the liquid crystal molecules have dielectric anisotropy and conductance anisotropy, the liquid crystal molecules will be oriented perpendicular to the surface of the substrate under the control of the electric field, but due to the interaction between the liquid crystal molecules and the physical forces such as gravity, The orientation of the liquid crystal molecules cannot be completely perpendicular to the surface of the substrate, thereby affecting the display effect of the liquid crystal display device. A liquid crystal display device of the prior art is shown in the first figure and the second figure. The liquid crystal display device 1 includes a first substrate 11 and a second substrate 12 disposed opposite to each other, and a first substrate 11 and a second substrate 12 therebetween. The liquid crystal layers 17 and 2 are respectively disposed on the first substrate 11 and the polarizing plates 110 and 120 on the opposite side of the substrate 12 and the liquid crystal layer, and the polarization axes (p〇iar] [zing Axis] are perpendicular to each other. The second substrate 12 is adjacent to the insulating layer 14 on the side of the liquid crystal layer 17 , the common electrode 15 disposed between the second substrate 2 and the insulating layer 51 , and the passivation layer 100 disposed on the π side of the insulating layer 14 adjacent to the liquid crystal layer. The signal line 13 and the pixel electrode 16 between the insulating layer 14 and the passivation layer 1 are disposed on the side of the passivation layer 100 adjacent to the liquid crystal layer 17 on the side of the liquid crystal layer 17 and the side of the substrate 11 adjacent to the liquid crystal layer 17 / side. The color filter 19 is an alignment layer 1〇1 disposed on the color filter 19 and adjacent to the liquid crystal layer. The common electrode 15 and the pixel electrode 16 are disposed between the two sides of the 配 aligning layer 1 〇 1 and for controlling the initial orientation of the liquid crystal molecules, and the alignment layers 101 and 102 are oriented in the same direction as the polarization axis of the polarizer 120. At least one of the first substrate 11 and the second substrate 12 is made of a transparent material, and the liquid crystal layer 17 is composed of Nematic liquid crystal. The liquid crystal display device 1 realizes color display through the color filter 19. Please refer to the first figure again, which is a schematic diagram of the working state of the liquid crystal display device 1 when no voltage is applied. In this state, since the liquid crystal molecules are oriented in the same orientation as the alignment layers 101 and 102 because they are not subjected to an electric field, the orientations of the alignment layers ι1 and 1〇2 are the same as the polarization axes of the polarizer 120. The linearly polarized light (not shown) entering the liquid crystal layer 17 through the polarizer 120 can pass through the liquid crystal layer 17, and the polarization state does not change. Further, since the polarization directions of the polarizers 110 and 120 are perpendicular to each other, the linearly polarized light cannot pass through the polarizer 110', that is, the liquid crystal display device 1 is in a dark state. Please refer to the second figure again, which is a schematic diagram of the working state of the liquid crystal display device when voltage is applied. The common electrode 15 and the pixel electrode 16 form an electric field 18 substantially parallel to the first substrate 11 and the second substrate 12. Since the liquid crystal molecules have dielectric anisotropy and conductance anisotropy, the liquid crystal molecules are under the action of the electric field 18 The orientation is the same as the direction of the electric field 18. However, if the direction of the electric field 18 is at an angle with the polarization direction of the polarizer 12〇, the linearly polarized light (not shown) passing through the polarizer 120 reaches the liquid 1282458 and the knife (4) is generated. The birefringence 'and thus the polarization state of the scalar polarized light will change, and the polarization axes of the sheets 110 and 120 are perpendicular to each other, so that part of the linearly polarized light will pass through the polarizer 11G, that is, the liquid crystal display is in a bright state. . As described above, the method of controlling the twist of the liquid crystal molecules by the electric field parallel to the substrate is called "In Plane Switching" (IPS), and the "in-plane switching method" phase is used for the plane_changing The liquid crystal display device 1 of the device has a wider viewing angle than the conventional liquid crystal display device. However, the insulating layer 14, the passivation layer 1 and the alignment layer 102 are present between the common electrode 15 and the liquid crystal layer 17, and The passivation layer 1 〇〇 and the alignment layer 102 ′ are present between the pixel electrode 16 and the liquid crystal layer 17 . Thus, the thickness of the common electrode 15 from the liquid crystal layer 17 is different from the thickness of the pixel drain 16 from the liquid crystal layer π, thereby When the voltage is applied, the common electrode 15 and the pixel electrode 16 have different grasping powers for the charged ions in the liquid crystal layer π, and therefore, the charged ions are concentrated to one side and are confined to the interface of the alignment layer 1〇2. When the voltage is not applied, the charged ions that are confined to the interface of the alignment layer 1〇2 are not converted to the next applied voltage after the release, and remain on the interface of the alignment layer 102 as the driving time increases. The number of electric ions is gradually increased, and a pair of liquid crystal layers 17 are formed to exert a cross-pressure, which affects the action of the liquid crystal molecules, thereby causing image sticking phenomenon, so that the image display effect of the liquid crystal display device is not good. The present invention provides a liquid crystal display device with better image display effect. Preferably, the present invention provides an in-plane switching liquid crystal display device including a first substrate and a second substrate disposed opposite to each other, and a first substrate and a second substrate disposed on the first substrate and the second substrate. a liquid crystal layer, at least one first alignment layer disposed between the first substrate and the second substrate, a common electrode disposed on the second substrate, and an insulation disposed on the first substrate and the side of the common electrode a layer, a pixel electrode disposed on the insulating layer, disposed on the insulating layer, and the image a passivation layer on the side of the electrode, the common electrode and the pixel a pole and the liquid crystal layer have the same distance, and the common electrode and the pixel electrode are provided with a transparent conductive film. The improvement of the above-described in-plane switching type liquid crystal display device is: setting The area of the flip-guide on the common electrode is larger than the area of the common electrode, and the area of the conductive film disposed on the pixel electrode is larger than the area of the pixel electrode. Compared with the prior reading, the in-plane switching of the present invention In the crystal display device, the distance between the common electrode and the pixel electrode and the liquid crystal layer is equal, so that when the voltage is applied, the common electrode and the pixel electricity (4) the grasping ability of the charged ion _, therefore, does not appear with the increase of the driving time The charged ions are concentrated on the interface close to the common electrode or the pixel electrode, that is, the cross-pressure of the image generated by the action of the crystal molecules is not generated, thereby preventing image sticking, that is, the flat (four) switching type liquid crystal display device 1282458 of the present invention has better The shadow axis shows the effect. Further, a transparent conductive film is disposed on the correction electrode and the pixel electrode to shield the electrode and the pixel electrode from the conductive wire to prevent interference. In addition, since the area of the transparent conductive film disposed on the common electrode is larger than the area of the common electrode, the area of the sun set on the pixel f is larger than the area of the pixel electrode, so when a voltage is applied, the common electrode is The electric field generated between the pixel electrodes is enhanced, so that a better display effect can be obtained at the same driving voltage. [Embodiment] A first embodiment of the in-plane switching type liquid crystal display device of the present invention is as shown in the third figure. The liquid crystal display device 2 includes a first substrate 21 and a second substrate 22 disposed opposite to each other. The liquid crystal layer 27 between the first substrate 21 and the second substrate 22 and the polarizers 210 and 220 respectively located outside the first substrate 21 and the second substrate 22 and having mutually opposite polarization axes are disposed on the second substrate 22. The common electrode 25, the insulating layer 24 disposed on the substrate 22 and the side of the common electrode 25, the pixel electrode 26 disposed on the insulating layer 24, the insulating layer 24, and the side of the pixel electrode 26 The passivation layer 200, the signal line 23 disposed between the passivation layer 2, and the alignment layer 202 disposed on the side of the purification layer 200 adjacent to the liquid crystal layer 27. The common electrode 25 and the pixel electrode 26 are spaced apart from each other, and both of them are adjacent to the alignment layer 202, and indium tin having the same thickness is disposed between the common electrode 25 and the pixel electrode 26 and the alignment layer 202 (Indium Tin) Oxide, ITO) film 250
