Abstract
To provide a flexible mold useful for manufacturing a PDP rib having a lattice pattern and other microstructures, and capable of highly precisely manufacturing the microstructures without involving defects such as occurrence of bubbles and pattern deformation. A flexible mold comprises a base layer made of a first curable material having a viscosity of 3,000 to 100,000 cps at 10 to 80° C. and a coating layer coating a surface of the base layer and made of a second curable material having a viscosity of 200 cps or below at 10 to 80° C.
Claims15
A flexible mold having a groove pattern having a predetermined shape and a predetermined size on a surface thereof, comprising:
- a flexible support film;
- a base layer disposed on the flexible support film the base layer made of a first curable material having a viscosity of 3,000 to 100,000 cps at 10 to 80° C.;
- a coating layer disposed on the base layer, the coating layer made of a second curable material having a viscosity of not greater than 200 cps at 10 to 80° C.
