ABSTRACT:
The present invention relates to a method of manufacturing a transflective liquid crystal display device including a color filter substrate having a plurality of pixels, each including a reflective display part and a transmissive display part, and retardation plates each built in areas on a principal surface of the color filter substrate opposed to a liquid crystal layer, which correspond to the reflective display parts. The manufacturing method is characterized by including in the following order: a first step of applying a photosetting resin composition on the principal surface of the color filter; a second step of partially curing areas of a photosetting resin film, which correspond to the reflective display parts, respectively, by light exposure through a mask; a third step of removing uncured portions of the photosetting resin film remaining in the second step by development; a fourth step of selectively forming unevenness in areas of a principal surface of the cured photosetting resin film, which correspond to the reflective display parts; and a fifth step of applying a material of the retardation plate onto the photosetting resin film having the unevenness, to form the retardation plates in the respective areas corresponding to the reflective display parts, by anchoring energy of a part having the unevenness, for the material of the retardation plate.
