Abstract:
1. A display device comprising: a drive circuit chip; and a substrate on which the drive circuit chip is mounted; wherein the drive circuit chip includes a semiconductor substrate, an insulation layer, a first conductive layer and a second conductive layer formed of metal between the semiconductor substrate and the insulation layer, and a first bump and a second bump formed over the insulation layer; wherein the first bump is superposed and electrically connected with the first conductive layer, and a profile of the first bump in plan view is within a profile of the first conductive layer in plan view; wherein the second bump is superposed and electrically connected with the second conductive layer, and a profile of the second bump in plan view is beyond a profile of the second conductive layer in plan view; and wherein the second bump is positioned at a corner portion of the drive circuit chip.
