Abstract: A display device includes a display panel, and a flexible printed circuit that is a wiring connected to a terminal on a glass substrate of the display panel, and transmitting an image signal. The display panel includes a master driver circuit element, a slave driver circuit element, and an inter-driver signal line that is a wiring on the glass substrate for conducting a communication between the master driver circuit element and the slave driver circuit element. The flexible printed circuit includes a connection terminal portion that is connected to the terminal on the glass substrate, and an electromagnetic wave blocking portion that extends from the connection terminal portion toward the display area side, and is arranged on the inter-driver signal line, and has a rear surface conductive pattern which is a planer conductive pattern formed on a surface facing the glass substrate.
