PROBLEM TO BE SOLVED: To provide a display device in which occurrence of noise in pulses being generated during the driving of the display device is prevented and deterioration of elements is suppressed and to provide a flexible substrate to achieve the above objectives. SOLUTION: The display device related to one embodiment of this invention includes a display panel on which electrodes are formed, a heat radiating plate formed on the back surface of the display panel, a driving board which is formed on the back surface of the heat radiating plate and a flexible substrate which is used to connect the electrodes and the driving board and is directly grounded to the heat radiating plate. Thus, occurrence of noise of the pulses supplied from the flexible substrate is prevented and deterioration of the flexible substrate is suppressed. COPYRIGHT: (C)2006,JPO&NCIPI
