In the invention, the resistance-capacitance delay is improved on the active elements.

Description

technical field [0001] The present invention relates to an array substrate, a manufacturing method thereof, and a display device, and in particular to an active component array substrate, a manufacturing method thereof, and a Liquid Crystal Display (LCD). Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor components or man-machine display devices. As far as display devices are concerned, flat panel display devices with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. Among various flat panel display devices, thin film transistor (Thin Film Transistor, TFT) liquid crystal display devices are currently the most mature flat panel display devices. [0003] However, there are still some problems to be improved in the development of the liquid crystal display device. One of t...

Problems solved by technology

However, when a voltage is applied to the scan line 104 and the data line 108, there will still be parasitic capacitance at the intersection 114, causing resistance-capacitance delay and affecting the display effect of the liquid crystal display device.

With the increase in the size of liquid crystal display devices, the data transmission speed is bound to increase, and the tolerance for resistance-capacitance delay is relatively poor.

Moreover, the length of the signal line also increases due to the increase in size, which in turn causes an increase in impedance, resulting in a higher resistance-capacitance delay
