Problems solved by technology
[0005] In the above-mentioned process of cutting the liquid crystal display panel, the inventor finds that the following problems can exist in the prior art: such as Figure 1-2 As shown, when the transmission mechanism transports the large slab 100, it may be clamped to the edge of the large slab 100. Since the auxiliary PS210 in the external redundant area of the sealant is usually set as an island-shaped or strip-shaped PS wall (wall) , the design of the island-shaped PS and PS wall is likely to cause PS peeling (peeling) when the large board 100 is transported. In addition, the auxiliary PS210 in the external redundant area of the sealant of each liquid crystal panel unit 110 is also prone to peeling when the large board 100 is cut. , PS peeling will cause poor foreign matter on the panel, which will affect the function and yield of the product

Embodiment Construction
[0032] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.
[0033] see Figure 4 to Figure 7 , the large liquid crystal panel to be cut of the present invention includes a TFT side panel 1 and a CF side panel 2 oppositely arranged, on which a plurality of cutting lines 9 are arranged;
[0034] The large liquid crystal panel to be cut is cut along the plurality of cutting lines 9 to form at least two liquid crystal panel units 10;
[0035] An auxiliary spacer layer 3 is provided between the TFT side large plate 1 and the CF side large plate 2;
[0036] Such as Figure 5 As shown, the auxiliary spacer layer 3 is planar and is interposed between the TFT side large plate 1 and the CF side large plate 2. Compared with the existing island and wall, the planar auxiliary spacer layer 3 The spacer can be mor...

Abstract
The invention provides a liquid crystal large board to be cut. The liquid crystal large board to be cut comprises a TFT side large board and a CF side large board, which are oppositely arranged, at least two liquid crystal panel units can be formed after the liquid crystal large board to be cut is cut, an auxiliary spacer layer is arranged between the TFT side large board and the CF side large board, the auxiliary spacer layer is planar and is sandwiched between the TFT side large board and the CF side large board, so that product abnormality caused by the drop of the auxiliary spacer layer inthe large board transmission and cutting processes can be avoided, thereby further improving the yield and quality of products.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a large liquid crystal panel to be cut. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel is composed of a color filter (ColorFilter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal and a sealant frame sandwiched between the color filter substrate and the thin film transistor array substrate. [0003] In the manufacture of liquid crystal display panels, several TFT array substrates are arranged on a large board with an entire surface, and similarly, several CF s...
