Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a circuit substrate formed from a thermoplastic liquid crystal polymer film which forms a melt phase of an optical anisotropy, and which has an excellent light reflectivity. SOLUTION: A circuit substrate at least includes a thermoplastic liquid crystal polymer film 11 which forms a melt phase of an optical anisotropy, a circuit layer 12 formed on one side of the thermoplastic liquid crystal polymer film 11, and a light reflective layer 13 thermally compressed and bonded onto the other side of the thermoplastic liquid crystal polymer film 11. The average light reflectance in a wavelength region of 400-500 nm is 50% or more. COPYRIGHT: (C)2011,JPO&INPIT
