Problems solved by technology

[0005] However, during the research process of the present invention, the inventors found that both of the above two solutions have certain defects: it is difficult to achieve a uniform distribution of glass spacers in the sealant, and it may cause two displays in places where glass spacers are densely packed. The gap between the substrates is large, while the sparse glass spacers lead to a small gap between the two display substrates
The non-uniformity of the cell thickness will lead to uneven distribution of the electric field between the display substrates, seriously affecting the display effect
Moreover, the conductive ball needs to be squeezed under an appropriate pressure to obtain a good conductive effect. If there is a difference in the thickness of the box, the conductive ball may not be able to play its conductive role due to too much or too little force

Abstract

The invention relates to a liquid crystal display (LCD) panel and a manufacturing method thereof. The liquid crystal display panel comprises two display substrates which are arranged opposite to each other, wherein a supporting spacer is formed at the edge of the surface of one display substrate by a composition process and contacted with the surface of the other display substrate; a frame sealing adhesive is also coated between the edges of the surfaces of the two display substrates; and a conducting material is doped in the frame sealing adhesive and / or the supporting spacer for electrically connecting the two display substrates. The manufacturing method comprises the following steps of: processing a high molecular material film layer by the composition process; forming a pattern comprising the supporting spacer at the edge of the surface of a functional film layer; coating the frame sealing adhesive; and folding up to ensure that the supporting spacer is in contact with the functional film layer of the second substrate. The supporting spacer is formed by the composition process, so that the position of the supporting spacer can be accurately controlled; and further, proper supporting force is provided for the liquid crystal display panel so as to keep the gap thickness between the liquid crystal display substrates and guarantee the display quality of the LCD.

Description

technical field [0001] Embodiments of the present invention relate to liquid crystal display technology, and in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] A liquid crystal display panel is an important display component in a liquid crystal display (LCD for short), and the LCD is widely used in various electronic devices due to its small size, light weight, high image quality and long lifespan. [0003] The structure of a typical liquid crystal display panel includes two display substrates, each of which is provided with a corresponding functional film layer. Usually, the two display substrates are a color filter substrate and an array substrate respectively. The two display substrates are arranged in a pair of boxes, and liquid crystal molecules are filled in them. In order to encapsulate the liquid crystal molecules, a sealant is coated on the edge of the display substrate for sealing. The two display su...
