Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device including the array substrate. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the flat panel display market. With the advancement of technology, consumers have put forward higher requirements for the display effect of mobile products, and the display effect of ordinary TN (Twisted Nematic, twisted nematic) liquid crystal display can no longer meet the market demand. At present, major manufacturers are gradually applying various wide viewing angle technologies with better display effects to mobile products, such as IPS (In-Plane Switching, coplanar switching), VA (Vertical Alignment, vertical alignment), AD-SDS (Advanced-Super Dimensional ...

AI Technical Summary

Problems solved by technology

[0005] However, in the current pixel structure, the thickness of the TFT area is different ( figure 1 The middle passivation layer 9 has obvious protrusions at the TFT) which affects the uniformity of liquid crystal molecule filling behind the cell, and the liquid crystal molecules are irregularly arranged in the reflection area; and because the pixel electrode inside the pixel structure is closer to the data line, Affected by the voltage of the data line, there is a step difference between the layers in the pixel area. This structure is not conducive to the horizontal driving of the ADS mode, and it is very easy to cause light leakage due to the insufficient deflection angle of the liquid crystal molecules due to abnormal liquid crystal driving (Disclination). , due to light leakage, the light emitted by the backlight cannot be fully utilized in the display area, resulting in low contrast of the panel and affecting normal use
