NOVELTY - The method comprises obtaining an impregnated member (101) by dipping an uncured resin material (3) in an aggregate of a glass fiber, obtaining a provisional cured product (102) by curing the uncured resin material, where the curing is performed by giving energy to parts excluding an outer edge part (12) of the impregnated member after a supporting member (71) is overlapped a side of the impregnated member, separating the supporting member from the provisional cured product, and obtaining a real cured product by curing a uncured resin material remained in the provisional cured product.    USE - The method is useful for manufacturing a transparency composite substrate, which is useful in an indication device substrate (all claimed) such as active matrix substrate and solar cell board, of an LCD device, an organic electroluminescent display device, a color filter, a thin film transistor, an electric paper and a touch panel.    ADVANTAGE - The method ensures efficient manufacture of the transparent composite substrate with high reliability, smooth surface, excellent heat resistance and good mechanical and optical properties and without deformation and the generation of the foreign substance thus improving the display quality and performance of the device    DETAILED DESCRIPTION - The method comprises obtaining an impregnated member (101) by dipping an uncured resin material (3) in an aggregate of a glass fiber, obtaining a provisional cured product (102) by curing the uncured resin material, where the curing is performed by giving energy to parts excluding an outer edge part (12) of the impregnated member after a supporting member (71) is overlapped a side of the impregnated member, separating the supporting member from the provisional cured product, and obtaining a real cured product by curing a uncured resin material remained in the provisional cured product. The aggregate of the glass fiber has an elongated phase. The method further comprises preparing liquid pellicle, coating the liquid pellicle with a covering material of an uncured surface of the cured product, fabricating an edge hardened film, peeling off the edge hardened film from the supporting member to obtain a coating layer, cutting a first resin material, dipping the first resin material into the aggregate of the glass fiber, solidifying the first resin material for obtaining a first resin layer, forming a second resin layer made of a second resin material on the surface of the first resin layer, and cutting the second resin material after the aging. The energy is a thermal energy or an optical energy. An INDEPENDENT CLAIM is included for a transparency composite substrate.
