Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel and a method of fabricating the same. [Prior Art] A liquid crystal display panel is a key component in a liquid crystal display device, and its main components include a two-substrate and a liquid crystal that is interposed between the two substrates. The principle of the liquid crystal display panel is that an applied voltage is applied to the substrate to form an electric field between the two substrates, and the liquid crystal molecules rotate under the electric field and control the passage of the light beam to display an image. The conduction of the two substrates is implemented by placing a conductive material around the sealant. FIG. 1 is a perspective exploded view of a liquid crystal display panel disclosed in the prior art. The liquid crystal display panel 1 includes a thin film transistor substrate 11, a color filter substrate 13, a liquid crystal layer 15, a plurality of columnar conductive pastes 16, and a sealant 17. The sealant 17 is coated on the thin film transistor substrate 11, and forms a receiving space with the thin film transistor substrate 11 and the color filter substrate 13. The liquid crystal layer 15 is received in the space, and the columnar conductive adhesive is 16 is disposed on the peripheral edge of the sealant 17. The color filter substrate 13 is stacked on the thin film transistor substrate 11, and the liquid crystal layer 15, the columnar conductive paste 16 and the sealant 17 are sandwiched between Between the two substrates 11, 13. The manufacturing method of the liquid crystal display panel 1 includes the steps of: coating the sealant 17 on the thin film transistor substrate 11 such that the sealant 17 is matched with the thin film transistor 11 to obtain a receiving space; and the thin film transistor substrate 11 is obtained. Dispersing a spacer (not shown), and injecting liquid crystal into the space formed by the sealant 17 200804938 and the thin film transistor substrate 11; the columnar conductive paste 16 is disposed on the periphery of the sealant 17 Aligning and bonding the color filter substrate 13 on the thin film transistor substrate 1]L in a vacuum environment, and sandwiching the liquid crystal layer 15, the columnar conductive paste 16 and the sealant 17 Between the two substrates 11, 13. In the liquid crystal display panel 1 , the conductive paste 16 is used as a conductive material to realize the conduction between the thin film transistor substrate 11 and the color filter substrate 13 , wherein the conductive adhesive 16 is a colloid doped with conductive silver ions. . However, in the manufacturing process of the liquid crystal display panel 1, since the control of the line of the sealant 17 has a great influence on the final display quality of the product, the conductive adhesive 16 disposed on the periphery of the sealant 17 may affect the sealant. The uniformity of I? causes the sealant 17 between the two substrates 11, 13 after pressing to be too wide or too narrow. In order to solve the problem of the uniformity of the line width of the sealant 17, the volume of the conductive particles of the column-shaped V-electrode 16 is reduced in the industry, and the coating is increased in order not to affect the conductivity of the columnar conductive paste 16. The gold of the columnar conductive paste 16 is a particle density. However, reducing the volume of the conductive particles increases the difficulty of coating, and increasing the density of the metal particles also increases the difficulty of coating and adjusting the glue.
