Semiconductor device and manufacturing method thereof

摘要

A display device comprising TFT elements having satisfactory characteristics and being easy to assemble. In the display device, a pixel emitting red light comprises a red color filter. The red color filter forms a light shielding film for the TFT elements in a driver circuit portion or in a pixel portion.
