Abstract
The present invention provides a reflection type liquid display device that does not cause defects such as a short circuit between a metallic reflection film and an electrode layer that are laminated on the substrate, a break in the electrode layer, and that can be easily manufactured because the alignment of elements is easily conducted. The reflection type liquid display device according to the present invention comprises a pair of substrates, a sealing member sandwiched by the pair of substrates, and liquid crystal sealed in a space surrounded by the sealing member and the pair of substrates, and is characterized in that many depressions and projections are formed on the surface of one substrate of the pair of substrates and a metallic reflection film and a flattening film are laminated on the depressed and projected surface, and that many depressions and projections are formed on the surface of the substrate at least other than an electrode terminal forming region and the surface of the substrate is made flat in the electrode terminal forming region.
