LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a liquid crystal display device of a transreflective type including a diffusion reflection electrode adapted to minute display. SOLUTION: The material prepared by mixing spherical particles PTC of an acrylic denaturation polystyrene of a specific gravity 1.00, a refractive index 1.50, and a particle diameter 1.6 μm into an organic resin film material PET containing an NQD as a sensitizing agent in an acrylic resin of a specific gravity 1.05 and a refractive index 1.50 and adjusting the mixture to a weight ratio 3:1, a total solid content 30% and a viscosity 20 mPa s is applied on an electrode and is dried. The material is exposed by using an exposure mask having an aperture for half exposure consisting of a number of slits in a portion to be the lower layer of the diffusion reflection electrode and is cured. Aluminum is sputtered thereon and is subjected to a photolithographic etching processing to form a diffusion reflection electrode MT in a reflection region. The reflection region of the diffusion reflection electrode MT has a surface rugged shape profiling the surface rugged shape by the spherical particles PTC mixed into the organic insulating film PF of the lower layer.
