1. A thermoplastic resin comprising a spatial structural component unit,
wherein the spatial structural component is a repeating unit derived from a diol compound represented by the following formula (a14) and/or a repeating unit represented by the following formula (9):

OG Complex Work Unit Chemistry
wherein Ar3 and Ar4 represent a phenyl group, L1 and L2 each independently represent a divalent linking group, m and n each independently represent 0 or 1, and W is at least one group selected from groups represented by the following formula (2) or (3):

OG Complex Work Unit Chemistry
wherein X represents a divalent linking group,
in a 0.1 mass % dichloromethane solution, the light transmittance at a wavelength of 355 nm is lower than 20% and the light transmittance at a wavelength of 500 nm is 90% or higher, and
when the thermoplastic resin comprises the repeating unit represented by the formula (9), the repeating unit represented by formula (9) is included at 10 mol % or greater and 20 mol % or less, based on the total repeating units.
