PROBLEM TO BE SOLVED: To provide a plastic substrate for a reflective liquid crystal display element which is characterized by being excellent in heat resistance and chemical resistance, having a low mean linear expansion coefficient and further excellent in surface smoothness. SOLUTION: The plastic substrate for the reflective liquid crystal display element contains a base material layer including fiber cloth and at least one layer of a smoothness improving layer to smooth the surface and has <=500 nm surface smoothness, (-5)-70 ppm mean linear expansion coefficient at 30-200 deg.C and 50-1,000μm thickness.
