    • A plastic substrate for display, having little coloration and excellent in optical characteristics, heat resistance, resistance to thermal coloration and mechanical properties, and a display element using the same are provided. The plastic substrate for display comprises a fumaric acid diester resin which comprises 60 mol % or more of a fumaric acid diester residue unit represented by the following formula (1): wherein R1 and R2 each independently represent a branched alkyl group or a cyclic alkyl group, having 3–12 carbon atoms, and has a number average molecular weight of 1,000–500,000 as determined by a gel permeation chromatography and converted into standard polystyrene, the substrate having a thickness 30–600 μm.
    • 提供了一种用于显示的塑料基板,具有很少的着色和优异的光学特性,耐热性,耐热着色性和机械性能,以及使用其的显示元件。 用于展示的塑料基材包括富马酸二酯树脂,其包含60mol%或更多的由下式(1)表示的富马酸二酯残基单元:其中R 1和R 2 各自独立地表示具有3-12个碳原子的支链烷基或环状烷基,并且通过凝胶渗透色谱法测定的数均分子量为1,000-500,000,并转化成标准聚苯乙烯,基材 具有30-600毫米的厚度。
