Abstract: According to an aspect, a display device includes: a substrate including a display region and a non-display region surrounding the display region; at least one driver IC including connecting terminals with a first surface fixed to face the non-display region; first wires supplying a signal to the display region; first bumps connected with the first wires; second wires transferring a signal to and from outside; second bumps connected with the second wires; and inspection wires. The connecting terminals of the driver IC include first connecting terminals overlapping the first or second bumps in plan view, and a second connecting terminal not overlapping the first or second bumps in plan view. At least one inspection wire includes a connecting conductor between itself and the second connecting terminal, and at least one fuse portion, a narrower width part of the inspection wire in plan view.
