Abstract:
1. A display device comprising: a display panel that includes a glass substrate as a base material and that conducts a display control based on a gradation value on each pixel in a display area; and a flexible printed circuit that is a wiring connected to a terminal on the glass substrate of the display panel, and transmitting an image signal, wherein the display panel includes: one master driver circuit element that is disposed outside of the display area, and applies a voltage corresponding to the gradation value to each pixel in the display area; at least one slave driver circuit element that is disposed outside of the display area, operates according to a command of the master driver circuit element, and applies a voltage corresponding to the gradation value to each pixel in the display area; 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, wherein the flexible printed circuit includes: a connection terminal portion that is a plurality of terminals connected to the terminal on the glass substrate; and an electromagnetic wave blocking portion that is arranged to extend from the connection terminal portion toward the display area side, and to cover 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, wherein a ground terminal of the master driver circuit element and a ground terminal of the slave driver circuit element are connected to a common terminal by the wiring on the glass substrate, and wherein the common terminal is electrically connected to a part of the connection terminal portion connected to the rear surface conductive pattern.
