Abstract
A liquid crystal display device 100 comprises a thin film transistor T, a source (data) line 26, a color filter 23, a pixel electrode 24 and the like. After a gate electrode 13, a gate insulating film 16, and a channel region 18 are formed on the glass substrate 10, a polyimide film 20 is formed to surround the peripheries of the region for forming the source/drain regions 22, the color filter 23, the pixel electrode 24, and the source line 26, respectively. A liquid material is applied to the regions surrounded with the wall made of the polyimide film 20 and a thermal treatment is performed to form the element of the color filter 23, the pixel electrode 24 and the like. The polyimide film 20 has a property of light-shielding and then has a function as a black matrix for shielding the surroundings of the pixel region.
