Provided is a display device including: a first gate line and a second gate line which extend in a first direction; a signal line and a current-supplying line which extend in a second direction intersecting with the first direction; a first sub-pixel surrounded by the first gate line, the second gate line, the signal line, and the current-supplying line; and a light-shielding film located over the first sub-pixel. The light-shielding film has a first opening portion and a second opening portion, and the first sub-pixel overlaps with the first opening portion and the second opening portion and has an emission region and a light-transmitting region. In the light-transmitting region, a distance in the first direction between the signal line and the current-supplying line continuously changes along the second direction.
