NOVELTY - A resin film comprises mold release agent inside. The mold release agents exist in surface other than other surface side in one surface side of the resin film.    USE - Resin film is used for laminate for manufacturing organic electroluminescent device substrate and color filter for flexible organic electroluminescent display (all claimed). Uses include but are not limited to flat panel display, touchscreen, electronic paper, color solar cell and flexible printed circuit board.    ADVANTAGE - The resin film has excellent peelability from support substrate, and provides flexible substrate without after-process defect.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) laminate, which has support substrate and the resin film;    (2) organic electroluminescent device substrate, which has organic electroluminescent element on surface on opposite side to surface side in which mold release agents of the resin film exist;    (3) color filter substrate, which has color filter on surface on opposite side to surface side in which mold release agents of the resin film exist;    (4) manufacture of resin film, which involves coating resin varnish containing mold release agent on support substrate, baking the coated resin varnish, forming resin film (f1), further coating resin varnish on the resin film (f1), baking the coated resin varnish, forming resin film (f2), and peeling the resin films (f1) and (f2) from support substrate;    (5) manufacture of flexible organic electroluminescent device substrate, which involves coating resin varnish containing mold release agent on support substrate, baking the coated resin varnish, forming resin film (f1), further coating resin varnish on the resin film (f1), baking the coated resin varnish, forming resin film (f2), forming organic electroluminescent element on the resultant resin film, and peeling the resin films (f1) and (f2) from support substrate;    (6) manufacture of flexible color filter, which involves coating transparent resin varnish containing mold release agent on support substrate, baking the coated resin varnish, forming transparent resin film (f1), further coating resin varnish on the resin film (f1), baking the coated resin varnish, forming transparent resin film (f2), forming black matrix and color pixel on resultant resin film, and peeling the resin films (f1) and (f2) from support substrate; and    (7) flexible organic electroluminescent display, which has the organic electroluminescent element and color filter.
