Abstract

To provide means for forming projected and recessed portions for preventing mirror face reflection of a reflecting electrode without increasing steps, in a method of fabricating a reflection type liquid crystal display device, to achieve light scattering performance by providing recessed and projected portions at a surface of a pixel electrode, projected portions 701 and 702 are formed by the same photomask as that in forming TFT to thereby form projected and recessed portions at a surface of a pixel electrode 169.
