Problems solved by technology

In particular, the connection of the data wiring to the common electrode causes the liquid crystal material therebetween to cause light to leak around the data wiring, thus degrading the quality of the image, and a black color is generally formed to prevent the leakage of light. Matrix (black matrix) is a reason for reducing the aperture ratio

Abstract

A gate line and a data line are formed on a first plate, and a pixel electrode is divided into several small parts through openings and a thin film transistor is formed on pixels defined by mutual intersections therein. A common electrode has a domain dividing opening, and data line openings are formed on a second plate opposite to the first plate. Removing the common electrode above the data line by forming the data line opening as described above results in a reduction in the load on the data line, reduces variation in liquid crystal capacitance, reduces light leakage due to side crosstalk, and increases Opening rate.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to a vertically aligned liquid crystal display to increase the viewing angle width by using a domain dividing device to divide a pixel area (area) into a plurality of small domains. Background technique [0002] Generally, a liquid crystal display (LCD), comprising an upper panel in which a common electrode and a color filter are formed and a lower panel in which a thin film transistor and a plurality of pixel electrodes are formed, and a liquid crystal material arranged therebetween, The display is a device that displays desired images by controlling the amount of light passing through each of the panels by applying an electric field to the liquid crystal layer. [0003] A plurality of wires including gate wires for transmitting scan signals and data wires for transmitting image signals are formed on the board of the thin film transistor, and are connected to surrounding wires or...
