A thin film transistor liquid crystal display (TFT LCD) panel, comprising an array substrate and a color filter substrate which are bonded together with a sealant, wherein a black matrix and a common electrode are formed on the color filter substrate, a data-line wiring is connected with a patterned pad for data-line signal output after being led out from an display region of the array substrate, a gate-line wiring is connected with patterned pad for gate-line signal output after being led out from the display region of the array substrate, and an opening structure is formed in the black matrix in a region where the color filter substrate overlaps with the data-line wiring.
