  • Patent number: 6327009
    Abstract: In a reflection-type liquid crystal display panel (10) provided with reflective electrodes (13a), a reflective metal film (13a) is formed on an insulating layer (12) having a surface provided with minute irregularities (17) to form the reflective metal electrodes having surfaces of a shape substantially complementary to the minute irregularities. Since the surfaces of the electrodes (13a) are provided with minute irregularities, external light incident on the liquid crystal display panel is not reflected in a specular reflection mode, so that images are displayed on the liquid crystal display panel in satisfactory visibility. The insulating layer is formed by forming a positive photosensitive resin layer on a back substrate (10a), exposing the positive photosensitive resin layer to light through a transparent sheet (18) having a surface provided with minute irregularities, and subjecting the exposed positive photosensitive resin layer to a developing process.
