A display device includes a display panel area with a plurality of pixels each including a switching element and gate lines and data lines connected to the pixels, a precharge circuit for applying a precharge voltage to the pixels to precharge the pixels, and at least two voltage transmission lines connected to the precharge circuit to transmit the precharge voltage. In this way, it is possible to test whether the data lines are short-circuited as well as if they are disconnected, in the VI test stage of a liquid crystal display of the SOG type, thereby increasing reliability.
