Patent ID: 7283130

Claim:
A display device comprising: an insulation substrate; a display region which is formed by arranging a plurality of pixels on a main surface of the insulation substrate; at least one drive circuit element which is mounted on a peripheral portion of the main surface of the insulation substrate and supplies signals or electric power to the display region; and a plurality of wiring lines which are formed on the peripheral portion of the main surface and have terminal portions thereof which are connected to the drive circuit element respectively formed on a mounting portion of the main surface on which the drive circuit element is mounted and which respectively extend to the outside of the mounting portion of the main surface, wherein the terminal portions which are respectively provided to the plurality of wiring lines are arranged in parallel along one end of the mounting portion such that the plurality of terminal portions are arranged close to one end of the mounting portion every one other, a plurality of bumps which are connected to the respective terminal portions by an anisotropic conductive film are arranged in parallel on a mounting surface of the drive circuit element which faces the mounting portion of the main surface in an opposed manner along one side of the mounting surface which faces one end of the mounting portion in an opposed manner, first bumps which belong to the plurality of bumps and are respectively connected to a group of terminal portions which are provided close to one end of the mounting portion are arranged closer to one side of the mounting surface than the plurality of respective bumps other than the first bumps, and second bumps which are different from the plurality of bumps are formed on the mounting surface close to the first bumps at one side of the mounting surface.
