Abstract:
1. A display device comprising: pixel transistors; a transparent organic insulating film covering said pixel transistors, and said transparent organic insulating film having contact holes; and transparent pixel electrodes extending over said transparent organic insulating film and within said contact holes and said transparent pixel electrodes being in contact with electrodes of said pixel transistors, wherein each of said transparent pixel electrodes has a variation in thickness, so that said thickness of said electrode over said transparent organic insulating film is thicker than said electrode within said contact hole, and said transparent pixel electrodes form a double-layered structure over said transparent organic insulating film and a single-layered structure within said contact hole, said double-layered structure extends over said transparent organic insulating film, a first layer of the double-layered structure extending over a terminal end of a second layer of the double-layered structure and into said contact holes, forming said single-layered structure within said contact hole, the second layer of the double-layered structure only extends in a horizontal plane, said single-layered structure having a bottom surface, said bottom surface in contact with a top surface of a first level interconnection layer formed with a drain thereby electrically connecting said transparent pixel electrodes with said drain.
