A display device includes: a display area; a terminal; and a wire formed between the display area and the terminal and connected to the terminal. The wire includes a first part, a second part, and a third part. The first part extends in a first direction. The second part and the third part extend in a direction different from the first direction. The first part is located between the second and third parts and includes a protruding portion protruding in a second direction perpendicular to the first direction.
