Abstract
A liquid crystal display device including first and second substrates, and a liquid crystal layer sealed therebetween. The device also includes a first electrode formed on the first substrate and a second electrode formed on the second substrate; a first molecule orientation film formed on the first substrate so as to cover the first electrode; a second molecule orientation film formed on the second substrate so as to cover the second electrode; a plurality of micro structures associated with at least one of the first and second electrodes; and a plurality of rough structural patterns associated with at least one of the first and second electrodes. At least some of the micro structures extend generally parallel to each other, and the rough structural patterns extend in directions different from directions in which the micro structures extend.
