ABSTRACT:
To provide an active matrix type liquid crystal display device having fine display performance, an interlayer insulating film104covering TFTs102, 103formed on a substrate101is first flattened by mechanical polishing typified by a CMP. Then pixel electrodes106, 107are formed thereon, and further, an insulating layer108covering the pixel electrodes is formed. And then, the insulating layer108is flattened by second mechanical polishing so that the surfaces of the pixel electrodes and the surface of the insulating layers112, 113form the same plane. By this, a difference in level disappears, and it is possible to prevent lowering of contrast or the like due to poor orientation of a liquid crystal material, diffused reflection of light, and the like.
