Problems solved by technology
A chip on film (Chip On Film) 700 is arranged on the gap position, and the buffer tape 530 is attached to the chip on film 700, which causes the buffer tape 530 to be peeled off when the chip on film 700 is reworked, and The viscosity of the buffer tape 530 is generally relatively high, so as to prevent the liquid crystal display panel 300 from jumping off from the front frame 500 due to the small viscosity of the buffer tape, which may cause the chip-on-chip film 700 to be peeled off at the same time when the buffer tape 530 is peeled off, thereby causing Abnormal problems such as bright lines appear on the liquid crystal display device

Embodiment Construction
[0035] In order to further illustrate the technical means and effects adopted by the present invention, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.
[0036] see Figure 5 , while referring to Image 6 and Figure 7 , the invention provides a method for manufacturing a liquid crystal display device, comprising the following steps:
[0037] Step 1. Provide a backlight module 20, a liquid crystal display panel 40, and a front frame 60. The liquid crystal display panel 40 includes a TFT substrate 42, a CF substrate 44 attached to the TFT substrate 42, and a CF substrate 44 disposed between the TFT substrate 42 and the CF substrate 44. Between the liquid crystal (not shown), a gap position 420 is formed between the edge position of the TFT substrate 42 and the edge position of the CF substrate 44. The gap position 420 is provided with several chip-on-chip films 421 at intervals. The chip-on-chip f...

The manufacturing method comprises the steps of: step 1, providing a backlight module (20), a liquid crystal display panel (40) and a front frame (60), the liquid crystal display panel (40) comprising a TFT substrate (42), a CF substrate (44) adhered to the TFT substrate (42) and liquid crystals arranged between the TFT substrate (42) and the CF substrate(44), a mismatch location (420) being formed between an edge location of the TFT substrate (42) and an edge location of the CF substrate (44), a plurality of chip on films (421) being arranged in the mismatch location (420) at intervals; step 2, adhering a buffer tape (423) to the mismatch location (420) of the TFT substrate(42) except the plurality of chip on films (421); step 3, assembling the liquid crystal display panel (40) onto the backlight module (20); and step 4, assembling the front frame (60) onto the liquid crystal display panel (40), the front frame (60) abutting on the buffer tape (423) of the liquid crystal display panel (40), and then manufacturing a liquid crystal display device.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method for manufacturing a liquid crystal display device and the liquid crystal display device. 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 displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module Refracted out to produce a picture. Since the liquid crystal display panel itself does ...
