Problems solved by technology

The second conventional technology aims to use the common electrode interconnection line as both a conductor and a shielding film, and it has never been stated what kind of structure is required to prevent electric field leakage from scanning lines and data lines with transparent electrodes
[0013] However, with the conventional technology, since the common electrode is formed with a shielding film, the utilization efficiency of the light beam in the device is lowered

Abstract

An in-plane switching mode liquid crystal display device includes a substrate, a scanning line formed on the substrate, a data line formed above the substrate to cross the scanning line while interposing an insulation film between the data line and the scanning line, and a transparent common electrode interconnect line located farther the substrate than the scanning line and the data line and having a width longer than those of the scanning line and the data line, and further, formed to geometrically cover the scanning line and the data line. The construction of the device makes it possible to make all electric fields from the data line and the scanning line terminate on the common electrode interconnect line. Forming the common electrode interconnect line with a transparent conductive material maintains the aperture ratio of the device.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to an in-plane switching (In-Plane Switching, IPS) mode liquid crystal display. Background technique [0002] There are two main types of LCD monitors. One of these two main types of displays displays images by rotating the long axis of the liquid crystal molecules (the direction of the axis is called the "director") in a plane perpendicular to the substrate. In contrast, the other displays images by rotating the long axes of the liquid crystal molecules in a plane parallel to the substrate. [0003] The former is called a twisted nematic (TN) liquid crystal display, and a typical example of the latter is an IPS liquid crystal display. [0004] The feature of this IPS liquid crystal display is that even if the viewer views the image displayed on the display from different directions relative to the display, since the viewer only views the liquid crystal molecules in the direction along ...
