Abstract
A reflective liquid crystal display device comprising a reflector with a number of small convex portions of the same shape is provided. The reflector is formed by patterning a photosensitive resin applied to one surface of a core substrate to a predetermined pattern so as to form a number of small convex portions, heat-treating the surface having the convex portions, and covering the surface with a reflective film. By suitably selecting the shape of the convex portions, the reflective properties of the reflector are controlled.
Claims7
A reflective liquid crystal display device comprising:
- an insulating substrate having a transparent electrode formed thereon;
- a reflector including a core substrate, a number of small convex portions formed on the core substrate by patterning a photosensitive resin applied to one surface of the core substrate by use of a photomask having a predetermined pattern, and a reflective film covering the surface of the core substrate having the convex portions;
- and
- a liquid crystal layer sandwiched between the insulating substrate and the reflector.
A method for fabricating a reflective liquid crystal display device provided with a reflector including a core substrate, a number of small convex portions formed on the core substrate and a reflective film covering the surface of the core substrate having the convex portions, the method comprising the steps of:
- patterning a photosensitive resin applied to one surface of a core substrate for the reflector by use of a photomask so as to form a number of small convex portions on the core substrate;
- heat-treating the core substrate having the convex portions;
- and
- forming a reflective film on the surface of the core substrate having the convex portions.
