An active matrix liquid crystal display device includes a thin film transistor substrate having a thin film transistor, an opposing substrate having an opposing electrode, a liquid crystal element interposed between the thin film transistor substrate and the opposing substrate, a protective film layer, a pixel electrode and a black matrix. By forming a protective film layer between the pixel electrodes and the black matrix, there is no negative influence on image quality even when the specific resistance of the black matrix is low. Also, Na contamination, and the like, from the dyes, and the like, used for the light-blocking material can be prevented. At this time, by etching the protective film layer using the pattern of the black matrix as a mask, one sheet is enough for the masks necessary for elimination of the protective film on the pixel electrode section. By this, it becomes possible to stop the increase of number of processes to a minimum. Furthermore, by performing etching of the protective film layer by anisotropic etching, rubbing defects caused by the processed shape of the black matrix can also be prevented.
