To provide a flexible mold (10) 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 (10) comprises a base layer (2) 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 (3) coating a surface of the base layer (2) and made of a second curable material having a viscosity of 200 cps or below at 10 to 80~C.
L'invention concerne un moule souple (10), qui permet de fabriquer une nervure de PDP à configuration de grille ou d'autres microstructures, ou de fabriquer avec précision lesdites microstructures, sans défauts, tels que des bulles ou une déformation du motif. L'invention concerne un moule souple (10), qui comprend une couche de base (2) constituée d'un premier matériau polymérisable dont la viscosité est comprise entre 3.000 et 100.000 cps à une température de 10 à 80 ·C, et une couche de revêtement (3) disposée à la surface de la couche de base (2) et constituée d'un second matériau polymérisable présentant une viscosité d'au plus 200 cps à une température de 10 à 80 ·C.
