    • A liquid crystal display device with improved image quality by reducing emphasized separation line corresponding to a divisional position, vertical faint stripes and lateral crosstalk caused by the displacement of divisional exposure of light in manufacturing a wired substrate of a liquid crystal display panel installed in an IPS liquid crystal display device. Compensating capacity patterns are provided to make parasitic capacities invariable irrespective of positions whether or not it is at the divisional position or the others. It is concerned with capacity between signal wire and its nearest common electrode wire formed on a substrate of a driving element side manufactured through the divisional light-exposing and installed in an active matrix display device. A liquid crystal material is driven by an electric field parallel to the substrate surface.

    • In a display device, electrodes of both an opposing-side substrate and a TFT-side substrate are made of transparent metals to improve the display device in light transmission rate. The display device operates in the same manner as that of a so-called In-Plate Switching type of liquid crystal display device. Sandwiched between the substrates is a liquid crystal having a negative dielectric anisotropy. A transparent electrode is formed on an opposing surface of the opposing-side substrate to face the TFT-side substrate. Pixel electrode portions and an interlayer insulation film are formed on an opposing surface of the TFT-side substrate to face the opposing-side substrate. The interlayer insulation film has its slits aligned in position with the pixel electrode portions.

    • Pairs of electrodes are disposed at a predetermined interval, each pair, which forms a unit, consisting of a lower comb-tooth-like electrode 103 and an upper comb-tooth-like electrode 107 which overlap each other by several micrometers. The electric field which is originated from the upper comb-tooth-like-electrode 107 is vertical on the surface of the electrode. In addition, with respect to the electric field which is originated from the lower comb-tooth-like-electrode 103, it is originated from the edge and the top flat portion thereof. In this condition, the electric field is vertical only in the vicinity of the upper comb-tooth-like-electrode 107 and the lower comb-tooth-like electrode 103. Moreover, the electric field which is originated from the edge of the lower comb-tooth-like electrode 103 extends within the insulation film layer 104 and the transistor protection film 108, and thus it is not applied to the liquid crystal. Therefore, since no vertical electric field exists in the space between the electrode pairs when the display is viewed from the front, through the space the light being transmitted, the transmitted light is uniform.
    • 每对电极以预定的间隔布置,形成一个由下梳齿状电极103和上梳齿状电极107组成的单元,该梳齿状电极103和上梳齿状电极107彼此重叠几微米。 来自上梳齿状电极107的电场在电极的表面上是垂直的。 此外,对于源自下梳齿状电极103的电场,其起源于其边缘及其顶部平坦部分。 在这种情况下,电场仅在上梳齿状电极107和下梳齿状电极103附近是垂直的。此外,源自下梳状电极107的边缘的电场 在该绝缘膜层104和晶体管保护膜108之间延伸的蓝牙状电极103不会施加于液晶。 因此,当从前方观察显示器时,在电极对之间的空间中不存在垂直电场,通过该透射光的空间,透射光是均匀的。
