A liquid crystal display device and manufacturing method thereof

Abstract

The invention discloses a liquid crystal display device and a manufacturing method of the liquid crystal display device. The liquid crystal display device comprises a first substrate, a second substrate, a first planarization layer, first photo spacers and second photo spacers, wherein the first substrate and the second substrate are arranged oppositely; the first planarization layer is located on the first substrate and provided with first deep holes and second deep holes; the first ends of the first photo spacers are arranged on the second substrate, and the second ends of the first photo spacers are arranged in the first deep holes and make contact with the bottoms of the first deep holes; the first ends of the second photo spacers are arranged on the second substrate, the second ends of the second photo spacers are arranged in the second deep holes, and gaps are reserved between the second ends of the second photo spacers and the bottoms of the second deep holes. By the adoption of the liquid crystal display device, the standing stability of the photo spacers can be enhanced, the phenomenon that light leaks or bright spots are broken due to sliding of the photo spacers can be relieved, the number of mask plates used in the process of preparing the liquid crystal display device can be reduced, the preparation process is simplified, and the preparation cost is lowered.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) has become a display technology that can span all sizes due to its small size, low power consumption, and no radiation. It is widely used in fields such as TVs and notebooks. computer, monitor or mobile phone etc. [0003] TFT-LCD is a liquid crystal cell formed by aligning and bonding the array substrate and the color filter substrate. A columnar spacer (Photot Spacer, PS) is used to maintain the cell thickness of the liquid crystal cell. At present, the main design method adopted for the PS in TFT-LCD is to apply the main PS (Main PS) and the auxiliary PS (Sub PS) to play a supporting role together, wherein there is a certain height difference between the Main PS and the Sub PS, and The number of Main PS is sma...

AI Technical Summary

Problems solved by technology

[0004] When the array substrate and the color filter substrate are aligned and bonded, due to the flatness of the standing position of the columnar spacer, the Main PS or Sub PS may slide into the through hole for electrically connecting the pixel electrode and the drain, resulting in Squeeze light leakage or crushed bright spots, and the gap between the array substrate and the color filter substrate is abnormal after the Main PS or Sub PS slips
