Problems solved by technology
[0003] In the manufacturing process of large-size displays, one side of the CF substrate is used as the electrical signal input terminal, which makes the array substrate with circuit faults such as short circuits cause abnormalities in all areas on the CF substrate after conducting with the CF substrate. It cannot be used as a product, which not only causes serious waste, but also seriously affects product yield
[0004] In the long-term research and development process, the inventor of the present application found that in the existing LOC (lead-on-chip) technology, the waste of resources is serious and the product quality is unreliable

Abstract
A liquid crystal display (10) and a fabrication method therefor. The method comprises: providing an array substrate motherboard (100) and a color filter substrate motherboard (200); detecting the array substrate motherboard (100) and marking a short-circuit region (110) of the array substrate motherboard (100); coating the array substrate motherboard (100) and / or the color filter substrate motherboard (200) with a conductive adhesive (120) and attaching the two motherboards together to obtain a composite substrate (300), wherein the short-circuit region (110) is not coated with the conductive adhesive (120); and curing the composite substrate (300).
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display and a preparation method thereof. Background technique [0002] With the continuous development of display technology, people's requirements for the performance of the display are constantly improving. The liquid crystal display using ITO film as the electrode of the CF substrate has become a research hotspot because of its good conductivity and high visible light transmittance. [0003] In the manufacturing process of large-size displays, one side of the CF substrate is used as the electrical signal input terminal, which makes the array substrate with circuit faults such as short circuits cause abnormalities in all areas on the CF substrate after conducting with the CF substrate. If it cannot be used as a product, it will not only cause serious waste, but also seriously affect the product yield. [0004] In the long-term research and development proces...
