A film-chip complex includes a film which includes a connection region along one side, a chip which is mounted on the film, a gate signal line which is disposed on the film, wherein the gate signal line includes a gate lead which is disposed in the connection region and a gate main line which connects the chip with the gate lead and a signal line which is disposed on the film, wherein the signal line includes a signal lead which is disposed in the connection region, a signal main line which extends substantially toward an exterior of the connection region and a signal pad which is connected with the signal main line.

Display device having film-chip complex including a film having a connection region along one side

Disclosed is a liquid crystal display device comprising a display part. The liquid crystal display device allows a common electrode voltage swinging depending on a gate off voltage of the display part to be fed-back through a feed-back circuit and to be held at a constant level, thus stabilizing the common electrode voltage and the gate off voltage coupled to a capacitance component, thereby preventing a picture displayed on the liquid crystal display panel from being divided into blocks. The common electrode voltage is detected at a position capable of being connected to the common electrode. The detected common electrode voltage is input into a comparator for outputting the common electrode voltage. The output of the comparator is controlled to thereby control the swing of the common electrode voltage.
