Abstract

A display device includes a substrate including a pixel area including a pixel; a peripheral area adjacent to the pixel area; and a boundary between the pixel area and the peripheral area, the boundary comprising a rounded corner; a data driver in the peripheral area; a data line through which a data signal is provided from the data driver to the pixel; and an initialization voltage source in the peripheral area and connected to the pixel, the initialization voltage source extended along the rounded corner of the boundary between the pixel area and the peripheral area. Along the rounded corner of the boundary, the initialization voltage source overlaps the data line along a thickness direction.
