Array substrate and manufacturing method

Abstract

The invention provides an array substrate comprising a substrate, a plurality of scanning lines, an active layer arranged on the scanning lines, a plurality of data lines interlaced with the scanning lines, a drain electrode contacted with the active layer, a passivation layer formed on the drain electrode and a pixel electrode formed on the passivation layer, wherein a scanning line hole is formed in positions, where the data lines are interlaced, on the scanning lines respectively; and in the lines interlaced with the scanning lines on the data lines, part of the lines are overlapped with the scanning line holes, and the other part of the lines are overlapped with the active layer and in overlapping joint with one another. The invention further provides a manufacturing method of the array substrate. Compared with the prior art, by forming the scanning line holes in the positions where the data lines are interlaced on the scanning lines, the overlapping area between the scanning lines and the data lines is reduced, then the parasitic capacitance is reduced and the influence of a vacuum voltage on panel display is reduced, so that the resistance value of the electric resistance of the scanning lines can keep unchanged while the aperture opening rate of a pixel electrode is improved.

technical field [0001] The invention relates to a liquid crystal display panel technology, in particular to an array substrate and a manufacturing method. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] Thin Film Transistor (TFT) liquid crystal display is the most common liquid crystal display in the mainstream market at present, and the TFT pixel design generally adopts a light-shielding structure design to reduce the problem of excessive leakage current caused by backlight illumination; the light-shielding structure One of the major drawbacks is the large parasitic capacitance, resulting in a large Feedthrough (vacuum) voltage, resulting in wrong writing of signals. At present, large-size panel...

Problems solved by technology

[0003] Thin Film Transistor (TFT) liquid crystal display is the most common liquid crystal display in the mainstream market at present, and the TFT pixel design generally adopts a light-shielding structure design to reduce the problem of excessive leakage current caused by backlight illumination; the light-shielding structure One of the major disadvantages is that there will be a large parasitic capacitance, resulting in a large Feedthrough (vacuum) voltage, resulting in incorrect signal writing

At present, large-size panels require the line width of the scanning lines to be as large as possible to drive the panel normally, but this will increase the parasitic capacitance of the data lines and scanning lines, resulting in RC delay (RC Delay, that is, the increase in capacitance and resistance causes delay Time), which will cause abnormal Flicker
