ABSTRACT:
A display device includes a display panel, and a semiconductor chip having plural bump electrodes and mounted on a substrate constituting the display panel. The plural bump electrodes include a first bump electrode arranged in the vicinity of a center for a longitudinal direction of the semiconductor chip, and a second bump electrode arranged in the vicinity of an end portion in the longitudinal direction of the semiconductor chip. The semiconductor chip has one or more than one conductive layer inside. Assuming that a surface of the semiconductor chip having the bump electrodes formed thereon is a lower side, the number of the conductive layers formed on the second bump electrode is greater than the number of the conductive layers formed on the first bump electrode. The conductive layer formed on the first and the second bump electrode includes a dummy conductive layer. Further, the plural bump electrodes are electrically connected to a wiring layer formed on a substrate constituting the display panel through an anisotropic conductive film.
