Abstract

The invention discloses a thin film transistor array substrate, a liquid crystal display and a display device. An existing vertical common electrode wire placed outside a display area is deleted so as to meet requirements of a narrow frame of the liquid crystal display; and meanwhile, at least one first common electrode wire electrically connected with the common electrode in the thin film transistor array substrate is arranged in the display area, resistance of the common electrode at a gap position between sub pixel units of adjacent array of each first common electrode wire can be reduced through setting the first common electrode wire, so that Greenish phenomenon of the liquid crystal display is improved. And the first common electrode wire can be arranged at a position close to an edge of the sub pixel unit, so that the effect of increasing aperture opening ratio is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor array substrate, a liquid crystal screen and a display device. Background technique [0002] In recent years, liquid crystal display devices have replaced traditional cathode ray tube displays and are widely used in many electronic products due to their advantages of thinness, lightness, power saving, and no radiation. [0003] In the thin film transistor (TFT) array substrate of the existing liquid crystal display, such as figure 1 As shown, there are multiple gate signal lines Gate and multiple data signal lines Data, and the area surrounded by any adjacent two gate signal lines Gate and any adjacent two data signal lines Data is a sub-pixel unit , each sub-pixel unit has a corresponding pixel electrode and a common electrode. In the display mode, the voltage of the pixel electrode is controlled by changing the electrical signal loaded on the gate sign...
