PROBLEM TO BE SOLVED: To provide a substrate for a sheet display featuring thickness reduction, weight reduction, impact resistance, flexibility, low thermal expansion characteristics, insulation property, and smoothness in combination. SOLUTION: The substrate for the sheet display formed with a resin layer on the surface of a sheet metal is preferably≤0.15μm in the surface roughness Ra of the sheet metal, is≤5.0μm in Ry,≤0.2% in the area rate of the non-metallic inclusions existing on the surface of the sheet metal, and is≤10μm in the maximum length of the non-metallic inclusions. Further preferably, the coefficient of thermal expansion from 30°C up to 300°C of the sheet metal is 1 to 11×10<SP>-6</SP>/°C. COPYRIGHT: (C)2005,JPO&NCIPI
