Abstract
There is provided an excellent contact between an electrode of a thin film transistor and a pixel electrode. A display device includes: an organic planarization film including a first contact hole opened on an electrode of a thin film transistor; an interlayer insulating film including a second contact hole opened on the electrode of the thin film transistor and on the organic planarization film; a base electrode that covers a portion where an end of the second contact hole overlaps a side wall of the first contact hole; and a pixel electrode contacted with the electrode of the thin film transistor.
