Array structure of transverse electric field effect type and its manufacturing method

Abstract

The invention provides an IPS liquid crystal display with a Cs line disposed in the vicinity of a gate line in which a flicker and image persistence of a liquid crystal display is suppressed by shielding influence of an electric field diverging from the gate line. In the IPS liquid crystal display, a pixel surrounded by a first common electrode line includes the gate lines laid on an insulating substrate in parallel to each other, a first insulating film covering the gate lines and a Cs line with a wing part laid on the first insulating film in parallel to the gate lines between the neighboring gate lines wherein the hollow wing part of the Cs line is laid in the proximity of the gate lines at the end parts.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to an IPS liquid crystal display which can shield the influence of an electric field from a grid line without lowering the aperture ratio, and is less likely to cause display burns. Background technique [0002] The IPS (In-Plane Switching) method used to obtain liquid crystals with a wide viewing angle makes the applied electric field parallel to the substrate surface, also known as the lateral electric field effect method. In the IPS method, the arrangement of liquid crystal molecules in the substrate plane is changed by turning ON / OFF of an electric field along the substrate. In addition, this characteristic change in molecular arrangement produces an epoch-making wide viewing angle that cannot be seen in longitudinal electric field effect methods such as the twisted nematic (Twisted Nematic; TN) method. Hereinafter, an IPS liquid crystal display is referred to as an IPS liqui...
