[0096] Please refer to Figure 10 , in another way of wiring the data line leads 121, all the data line leads 121 are located above the insulating layer 100I. At this time, the second spacer 123 is disposed on the insulating layer 100I below the data line lead 121 , that is, the second spacer 123 is located between the insulating layer 100I and the data line lead 121 . At this time, the data line leading film layer 120 at the position of the second spacer 123 includes the insulating layer 100I, the second spacer 123 , the data line lead 121 and the passivation layer 100P from bottom to top.

no. 3 example

[0098] Please refer to Figure 11 , the data line lead 121 is still all located above the insulating layer 100I, and the third pad 124 is arranged under the insulating layer 100I below the data line lead 121. At this time, the data line lead film layer 120 at the position of the third pad 124 is removed from From bottom to top are the third spacer 124 , the insulating layer 100I, the data line leads 121 and the passivation layer 100P.

Abstract

The invention provides an array baseplate used for a liquid crystal display device. The centre of the array baseplate is an display area; non-display areas are arranged at the periphery of the display area; a gate electrode drive circuit and lead wires are arranged in the non-display areas; a gate electrode drive circuit film layer is formed in the area of the gate electrode drive circuit; a lead wire film layer is formed in the area of the lead wires; the lead wire film layer comprises an insulation layer, a passivation layer, a plurality of lead wires extending in the same direction, and further comprises one or a plurality of heightening sheets, wherein the insulation layer is positioned at the upper part of the non-display area of the array baseplate; the passivation layer is positioned at the upper part of the insulation layer; the lead wires are positioned at the upper part and / or the lower part of the insulation layer; and the heightening sheets, the insulation layer, the passivation layer and the lead wires are overlaid layer by layer. According to the array baseplate for the liquid crystal display device provided by the invention, the heightening sheets are additionally arranged in the lead wire film layer, so that the height difference of the non-display areas at the periphery of the array baseplate is reduced or eliminated, and the quality of a display picture of a liquid crystal display is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an array substrate used for a liquid crystal display device. Background technique [0002] Flat-panel displays are the mainstream displays at present. Liquid crystal flat-panel 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] A liquid crystal flat panel display includes a liquid crystal panel, and usually a liquid crystal panel is composed of an array substrate, a color filter substrate, and liquid crystal encapsulated between the two substrates. [0004] In the past, a driver chip made of silicon wafers was usually externally connected to the array substrate, but now, the technology of directly integrating and manufacturing the gate driver IC on the gate line lead area of ​​the array substrate has been ...
