ABSTRACT:
A pixel portion100of a liquid crystal display device comprises a thin film transistor T comprising a channel region18,and source/drain regions22,a source (data) line26for supplying current to the thin film transistor T, a color filter23,and a pixel electrode 24. In forming the pixel portion100,a gate electrode13,a gate insulating film16and the channel region18are first formed on a glass substrate10.On the glass substrate10after the formation of the channel region18is formed, a wall made of a polyimide film20surrounding the peripheries of the regions for forming the source/drain regions22,the color filter23,the pixel electrode24and the source line26.Liquid materials are applied to the regions surrounded with a wall made of the polyimide film20,and a heat treatment is carried out to form films, thereby forming elements such as the color filter23or the pixel electrode24.
