ABSTRACT:
A liquid crystal display device includes a liquid crystal display panel obtained by adhering upper and lower polarizing plates to upper and lower surfaces, respectively, of an electrode substrate. The upper polarizing plate has a first roughened surface on its outer surface. The first roughened surface is formed for the purpose of antiglare. The lower polarizing plate has a second roughened surface on its outer surface. The second roughened surface is formed to have a surface roughness equivalent to or less than that of the first roughened surface. As a result, a moiré fringe is decreased.
