Problems solved by technology

[0007] The prior art has the following problems: the frame area 30 is used to accommodate the scanning connection lines 21. With the increasing resolution of liquid crystal displays and the miniaturization of liquid crystal display devices, it is necessary to reduce the area of ​​the frame area 30 to improve the utilization rate of the liquid crystal panel.
Therefore, there is not enough space in the frame area 30 to accommodate a plurality of scanning connection lines 21

[0051] refer to Figure 4 , is a schematic top view structure diagram of the array substrate according to the first embodiment of the present invention.

[0052] The array substrate is divided into a display area and a frame area surrounding the display area. To simplify the illustration, Figure 4 Only a schematic top view of a part of the display area is shown in . The display area includes: a glass substrate (not shown in the figure); a plurality of scanning lines on the glass substrate: scanning line 101, scanning line 103, scanning line 105, etc.; a plurality of data lines: data line 102, data Line 104, data line 106, etc., each scan line is orthogonal to the data line and is insulated from each other. The data line and the scan line are made of different layers of metal and are separated by an insulating medium layer. The data line is located above the scan line, and the two will display The area is divided into a plurality of pixel areas arranged in an array, and each...

[0087] In the above embodiments, the scan connection lines are directly connected to the scan lines through via holes in the display area, which is easily limited by wiring during actual manufacturing. As another optional embodiment, the scanning connection line and the scanning line may also be indirectly connected through a via hole located thereon and other layer metals located in the via hole.

[0088] Specifically, refer to Figure 18 As shown in FIG. 2 , it is a schematic top view structure diagram of the array substrate according to the second embodiment of the present invention. Will Figure 18 and Figure 4 It can be seen from the comparison that the difference between this embodiment and the first embodiment is only that the connection structure between the scanning connection lines and the scanning lines is indirectly connected through other metal layers.

[0089] For a better description of the above connection structure, please refer to Figure 19 ,for Figur...

no. 3 example

[0098] In the above embodiments, the scanning connection lines are located between the first pixel electrode and the second pixel electrode, that is, at the center of the pixel area. As another optional embodiment, the scanning connection lines can also be located in a part of the pixel area. side, and adjacent to the data line of the adjacent pixel area.

[0099] Figure 24 It is a schematic top view structure diagram of the array substrate according to the third embodiment of the present invention. to combine Figure 24 and Figure 4 As shown, the only difference between this embodiment and the first embodiment is that the scanning connection line is located between the pixel electrode and the data line in the adjacent pixel area. Specifically, the scanning connection line 202 is located between the first pixel electrode 1201 and the data line 104, and is located below the second transparent electrode 130 and parallel to the data line 104; the scanning connection line 203...

Abstract

The invention provides an array substrate, a manufacturing method thereof, and a liquid crystal display device, wherein the array substrate comprises a display area and a border area surrounding the display area; the display area comprises a plurality of orthorhombic and insulated data lines and scanning lines; the data lines and the scanning lines divide the display area into a plurality of pixel areas with ordered arrays; each pixel area internally comprises a pixel electrode, a common electrode, a thin film transistor, a first transparent electrode arranged above the pixel electrode and equipotential with the pixel electrode, a second transparent electrode arranged above the common electrode and equipotential with the common electrode, and a plurality of scanning connection lines which are used for electrically connecting each scanning line with an external drive chip; and the second transparent electrodes are located above the scanning connection lines. The area of the border area can be saved, and the utilization rate of the substrate is improved.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to an array substrate with a narrow frame design for reducing the frame width of a coplanar conversion type liquid crystal display device, a liquid crystal display device and a manufacturing method thereof. Background technique [0002] Flat-panel displays are currently the most popular displays, among which liquid crystal displays are widely used in electronic products such as computer screens, mobile phones, personal digital assistants, and flat-screen TVs because of their thin and light appearance, power saving, and no radiation. [0003] figure 1 is a schematic cross-sectional view of an existing liquid crystal display device, such as figure 1 As shown, a liquid crystal display device generally includes a color filter substrate 1 and an array substrate 3 disposed opposite to the color filter substrate 1 , and a liquid crystal layer 2 is sandwiched between the color filter subs...
