Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel and a method of fabricating the same, and more particularly to a liquid crystal display panel and a method of fabricating the same. [Prior Art] In recent years, liquid crystal display devices have gradually replaced conventional video tube (CRT) displays as display terminals of various types of electronic devices, and such liquid crystal display devices generally include a liquid crystal display panel composed of two upper and lower substrates. And a liquid crystal is injected between the two substrates; when different electric fields are formed between the two upper and lower substrates to change the inclination or position of the liquid crystal, the direction of light passing through the liquid crystal and the amount of light can be controlled, and at least one of the substrates is further Set polarizers and / or color filters. Since the foregoing substrate can be made of a transparent plate, glass, transparent plastic or the like, in order to make it electrically conductive, such as to generate an electric field effect, it is necessary to fabricate some active elements such as a Thin Film Transistor (TFT) on the surface of the substrate. Conventional thin film transistor liquid crystal display devices generally include the following processes: ❹ (1) Thin film transistor array substrate process. A thin film transistor is fabricated on a glass substrate to form a thin film transistor array substrate.

In the foregoing panel process, on the non-display area of the thin film transistor array substrate, there is included a predetermined area for combining with the color piece, and a plurality of (four) lines are disposed thereon. In order to protect the conductive lines, an appropriate amount of colloidal coffee is usually applied on the conductive lines to prevent the circuit from being rotted. Due to the fluidity of the colloids and the diversity of the specifications of the thin film electro-ceramic substrate, The coating does not have a standard, so that if the amount of victory is insufficient to cover all the conductive lines, the reliability of the product is likely to decrease. Conversely, if the coating is excessive, the thickness of the plastic can be too large, or even the rubber overflows. The latter part of the mold she installed bad, product assembly scrapped and other issues. SUMMARY OF THE INVENTION The present invention provides a liquid crystal display panel and a method of fabricating the same, which can effectively protect a conductive line by using a colloid and prevent the glue from overflowing, thereby improving product reliability and post-assembly yield.
