Abstract
A liquid crystal display panel and fabricating method thereof. The present invention forms the dummy lines in the areas separating the gate lines extended to the dummy area from the image display part of the liquid crystal display panel with the same opaque metal material of the data lines and the other dummy lines in the areas separating the data lines with the same opaque metal material of the gate lines. Thus, the dummy lines block the light. Therefore, the present invention minimizes the generation of the spot degradation caused by the scratches on the black matrix or the particles attached/detached to/from the black matrix in the dummy area as well as reduces the time taken for checking the spot degradation, thereby increasing quality of display and productivity.
