The present invention provides a transflective liquid crystal display device which includes diffusion reflective electrodes suitable for a display of high definition. Into an organic resin film material PET which is formed by mixing NQD as a photosensitive agent in an acrylic resin having a specific gravity of 1.05 and a refractive index of 1.50, spherical particles PTC made of acrylic modified polystyrene which has a specific gravity of 1.00, a refractive index of 1.50 and a particle size of 1.6 μm are mixed at a rate of 3:1 so as to form an organic insulation film material in which a total solid content is adjusted to 30% and viscosity is adjusted 20 mPa·s. The organic insulation film material is applied and is dried to form an organic insulation film. A portion of the organic insulation film which is to be arranged below a diffusion reflective electrode is exposed using an exposure mask having half exposure apertures which are formed of a large number of slits and the organic insulation film is hardened. Aluminum is sputtered to the organic insulation film and is subject to photolithography etching treatment thus forming the diffusion reflective electrodes MT in a reflective region. A reflective region of the diffusion reflective electrode MT has an uneven surface shape which traces uneven surface shapes of the spherical particles PTC mixed into the organic insulation film PF arranged below the diffusion reflective electrodes MT.
