<P>PROBLEM TO BE SOLVED: To provide an optical member capable of maintaining a high-performance antireflection effect on a substrate for a long period of time. <P>SOLUTION: The optical member comprises a laminated body, in which at least one layer is a polyimide layer containing a polyimide. The polyimide contains a repeating unit expressed by general formula (1), wherein 90 mol% or more of 1,4-cyclohexylene groups included in a main chain of R<SB POS="POST">2</SB>in the general formula (1) are trans-1,4-cyclohexylene groups. In the formula, R<SB POS="POST">1</SB>represents a tetravalent organic group; R<SB POS="POST">2</SB>represents a divalent organic group having one or two or more 1,4-cyclohexylene groups in the main chain. <P>COPYRIGHT: (C)2012,JPO&INPIT |
