Liquid crystal display device

To provide a technique whereby flicker and other display defects can be suppressed without restricting the arrangement of data lines in a liquid crystal display device having a non-rectangular displayregion. The liquid crystal display device is provided with an active matrix substrate (10), an opposing substrate, and a liquid crystal layer. The active matrix substrate (10) is provided with a plurality of gate lines (11) and a plurality of data lines (12). Pixel electrodes (14) are disposed in pixels defined by the gate lines (11) and the data lines (12), and a shared electrode (15) is provided in a display region (R). A capacitance formation part (C) for forming a capacitance between the shared electrode and a portion of the gate lines (11) from among the plurality of gate lines (11) is provided on an outside of the display region (R). The portion of the gate lines (11) have a smaller length than that of a largest gate line and intersect with a portion of the data lines (12) from among the plurality of data l
