Abstract: A display device includes a light emitting electrode on a thin film transistor layer. The thin film transistor layer includes a lower metal layer on a substrate and a semiconductor layer above and overlapping the lower metal layer. The lower metal layer includes a plurality of curved portions. Edges of respective ones of the curved portions are on concentric circles having substantially a same center point and an edge of the semiconductor layer is on the lower metal layer.
