## Abstract

A display device includes a substrate including pixel electrodes, a first data line extending in the first direction and through which a data signal is supplied to the pixel electrodes in a first region that is close to one ends of the pixel electrodes in the first direction, and a second data line extending in the first direction and through which a data signal is supplied to the pixel electrodes in a second region that is closer to another ends of the pixel electrodes in the first direction than the first region is, and a driver circuit disposed close to the one ends of the pixel electrodes and configured to supply a data signal to each of the pixel electrodes through the first data line and the second data line. The first data line and the second data line are overlapped with each other in the first region.
