A liquid crystal display panel includes a display region, a periphery circuit region, a joint obligate region, a plurality of first test thin-film transistors (TFTs), a plurality of second TFTs, a plurality of first lines, a plurality of second lines, a blank region, and at least one first adjustment TFT. The first and second test TFTs are disposed on the joint obligate region according to a regular distance. Each of the first and second test TFTs has a transistor width. The first adjustment TFT is disposed on the blank region. The width of the blank region is not smaller than the sum of the twice regular distance and the transistor width. Thereby, the present invention can prevent the band mura of the liquid crystal display panel effectively when the liquid crystal display panel is in testing.
