Abstract:
1. A liquid crystal display panel comprising: a pair of substrates arranged opposite to each other with a liquid crystal layer sandwiched therebetween, one of the pair of substrates including wherein the upper electrode includes plural slits formed in each pixel area sectioned in a row direction and a column direction by the scanning line and the signal line in the display area in planar view, wherein one of the upper electrode and the lower electrode is electrically connected to the common wiring line and operates as a common electrode, wherein in the display area, a common line is formed along the scanning line, the common line is made of a light shielding metal material, and the electrode operating as the common electrode is electrically connected to the common line through a contact hole in each pixel area, and the common line is electrically connected to the common wiring line at the peripheral edge portion of the display area, wherein the common line has a connection portion that is electrically connected to the electrode operating as the common electrode, wherein a width of the connection portion in the row direction is wider than a maximum width of the contact hole in the row direction, and a width of the connection portion in the column direction is wider than a maximum width of the contact hole in the column direction, and wherein the connection portion is formed at a position in which the connection portion overlaps with the contact hole in planar view so as to shield an opening of the contact hole.
