Abstract
A highly reliable reflection type liquid crystal display device having an organic film is disclosed in which generation of cracks in an electrode layer caused by the sinking in of the terminals of a driving element are prevented. A reliable electrical connection is thereby established between the driving element and the first electrode layer and the organic film is prevented from being separated from the substrate. The reflection type liquid crystal display device includes a pair of substrates, a seal material held between the pair of substrates, and a liquid crystal layer sealed in the space surrounded by the pair of substrates and the seal material. The organic film, which has a plurality of protrusions and recesses, a metal reflection film, an overcoat film, and first electrode layers sequentially formed on the surface of one of the pair of substrates. The organic film and the metal reflection film are formed in a display region but are not formed in a driving element mounting region.
