An alignment film 3 is formed thereon by offset printing and baked to form a film. Next, the alignment film 3 is rubbed with a cloth in a predetermined direction to perform an alignment treatment, and then an epoxy adhesive having a predetermined gap material as a sealing material is screen-printed on one of the substrates, and the space is spread on the substrate. The substrate was sprayed by a wet spray method and the two substrates were adhered to each other. The spraying density of the spacer was 150 co / mm 2 . Next, the liquid crystal 6 was filled by a vacuum injection method, and the injection part was sealed with an epoxy adhesive. This liquid crystal cell is sandwiched between an upper polarizing plate 7 and a lower polarizing plate 8, and a reflecting plate 9 provided with a color coating layer 10 on the lower polarizing plate is installed. The color coating layer is formed by coating a part or the entire surface of a rolled aluminum foil having a thickness of 15 μm with a resin containing a pigment and a dye by gravure printing and adhering a PET film (50 μm) thereto. As the pigment, for example, "Sericor EG fluorescent ink 104 or 139" manufactured by Teikoku Ink Mfg. Co., Ltd. can be used.
