Liquid crystal panel and manufacturing method thereof

摘要

A manufacturing method of a liquid crystal panel, including: manufacturing a first substrate and a second substrate; mixing sealant with alloy particles having low melting points, coating the mixture on the first substrate, and dropping liquid crystals on the first substrate; and bonding the first substrate and the second substrate, heating the two bonded substrates, and then cooling the substrates. Therefore, the manufacturing method can prevent the present golden balls from piercing the common electrodes and further prevent the short circuit of the circuit on the substrate, which improves the yield rate of the liquid crystal panel. Additionally, since the alloy particles are small sized, after the separate alloy particles melt, contacting points between the alloy particles and the common electrodes are increased. Also, contacting resistance between alloy particles, and the contacting resistance between the alloy particles and the substrate are reduced, which improves the conductivity between the common electrodes.
