Apparatus and method for a liquid crystal display device having an electrically-conductive light-shading layer formed on a smoothed layer

摘要

To improve the light-shading performance of an electrically-conductive light-shading layer in a liquid crystal display device including polycrystalline SiTFT made on a quartz glass substrate for driving a pixel electrode, and including the electrically-conductive light-shading layer located in a level above the polycrystalline SiTFT and below the pixel electrode, the electrically-conductive light shading layer is stacked on a smoothed inter-layer insulating film which is smoothed by CMP, for example.
