1. A display device, comprising:

  • a substrate having a display region so that signal lines formed within said display region are connected to respective terminals in a terminal group formed outside said display region via terminal wires; and

    an IC driver having bumps respectively facing and being connected to said terminals via an isotropic conductive film, characterized in thatsaid terminals are arranged in multiple staggered places in the direction in which said terminal wires run,in the case where one of the adjacent terminals, which are located at the same position, is a first terminal and the other is a second terminal, the regions where said first terminal and said second terminal are formed have a first portion of a terminal wire that is wider than the other portion and a second portion of the terminal wire which is adjacent to said first portion in the direction in which said terminal wire runs, and the first portion and the second portion in the region where said first terminal is formed and the first portion and the second portion in the region where said second terminal is formed are staggered,said first terminal and said second terminal are formed of a transparent conductive film made of a wide portion for covering the contact hole created above the first portion of the terminal wire and a narrow portion provided so as to overlap the second portion of the terminal wire from above,the other terminal wire adjacent to said first portion is formed so as to be bent in order to avoid interference with said first portion, andthe bump of said IC driver connected to said first terminal has a wide portion corresponding to the wide portion of said first terminal and a narrow portion corresponding to the narrow portion of said first terminal, and the bump of said IC driver connected to said second terminal has a wide portion corresponding to the wide portion of said second terminal and a narrow portion corresponding to the narrow portion of said second terminal.
