[0007] Although there is silica gel 109 at the terminal portion of the substrate 101 in the above-mentioned liquid crystal display device, since the entire protective electrode corrosion operation is carried out in air at normal temperature, and the curing time is relatively long, generally about 30 minutes, so that the moisture in the air is easily absorbed by the silica gel. Wrapped on the surface of the substrate 102, making this part more prone to electrode corrosion
Moreover, experiments have proved that during the silicone sealing process, if there is liquid moisture in the terminal part of the substrate, the liquid crystal display device will only continue to work for 1 to 2 minutes, and electrode corrosion will occur on the surface of the terminal.
Therefore, it is more difficult to use silica gel to prevent electrode corrosion and to protect liquid crystal display devices from corrosion.

Embodiment Construction
[0028] Please refer to the attached image 3 As shown in -7, the LCD substrate wiring is omitted in the figure, the first transparent substrate 101 and the second transparent substrate 102 face each other, and a sealed cavity is formed by a sealing material 111, and a liquid crystal 103 is sealed in the sealed cavity. A first transparent electrode 105a is formed on the inner side of the substrate 101, a second transparent electrode 105b is formed on the inner side of the second transparent substrate 102, and an alignment layer is formed on the side of the first transparent substrate 101 and the second transparent substrate 102 that is in contact with the liquid crystal. 104. The length of the second transparent substrate 102 is greater than that of the first transparent substrate 101, so a part of the second transparent substrate 102 is in the sealed cavity to form a substrate terminal, and the substrate terminal usually carries the driver IC 108 and the connection between the...

The invention discloses a method for preventing electrode corrosion and a liquid crystal display manufactured by the method, comprising the following steps: before bonding a drive IC, attaching a resin layer matching the distribution shape and size of the terminal electrodes on the terminal electrodes; The resin layer is thermally cured on the terminal electrodes. The invention quickly seals the space around the electrodes in a high-temperature environment, thereby reducing the contact between the electrodes and environmental moisture and ions to prevent electrode corrosion, effectively protecting the electrodes, and thereby reducing the failure rate of liquid crystal displays.
Description
【Technical field】 [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display device capable of preventing electrolytic corrosion of the exposed electrode leads connected between the substrate lead wires and the driving IC at the terminals of the liquid crystal display device. 【Background technique】 [0002] Currently, liquid crystal display devices are usually figure 1 shown. [0003] In this liquid crystal display device, a pair of substrates 101 and 102 sandwich a liquid crystal layer. The substrate 102 draws out all the wiring in the entire liquid crystal display device through the indium tin oxide thin film (ITO) on its surface. The driver IC 108 and wiring are connected through an anisotropic conductive film (ACF: Anisotropic conductive film) 106 . In addition, a flexible printed circuit board (FPC: Flexible Printed Circuit) 107 that supplies a driving signal to the driving IC 108 must be connected to the driving IC 108 throug...
