Abstract
To broaden a substantial area for wiring between a display portion and a driver element, and to increase the number of wirings between the driver element and the display portion. In a driving IC 100, bumps 10, 12, 14, 16, 18, 22, 24, 26 and 28 are arrayed in a first row 110 and bumps 11, 13, 15, 17, 21, 23, 25, 27 are arrayed in a second row 120, wherein the respective bumps are disposed so that the shortest distances between forward ends of the respective bumps and a side along the array, become larger gradually from the center outward in the array.
Claims9
A driver element having a rectangular shape, to be mounted on a display device containing a display portion, comprising:
- bumps that are arrayed in an array within a perimeter of the rectangular driver element and along a side of the rectangular driver element which is located close to the display portion when mounted, the respective bumps are disposed so that shortest distances between forward ends of the respective bumps and the side that is along the array, become larger gradually from a center outward in the array, and when mounted, the respective bumps are connected to the display portion by respective wires of a wiring portion and the side of the rectangular driver element is positioned so that the perimeter of the rectangular driver element contains a different length section from each of the respective wires that are connected to the respective bumps positioned between the center and a farthest end from the center in the array.
