    Abstract: It is an object of this invention to provide an optical member that is able to cut ultraviolet rays without employing means such as addition of an ultraviolet absorber to the resin, using an ultraviolet cut filter or using ultraviolet absorption coating, as well as a thermoplastic resin to be used for the optical member. The thermoplastic resin of the invention comprises a spatial structural component unit, wherein the spatial structural component unit includes four or more aromatic groups selected from the group consisting of monocyclic aromatic groups and fused polycyclic aromatic groups, the spatial structural component unit has three or more monocyclic aromatic groups and/or heterocyclic aromatic groups in a conjugated structure, or one or more monocyclic aromatic groups and one or more fused polycyclic aromatic groups in a conjugated structure, or two or more fused polycyclic aromatic groups in a conjugated structure, and 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.

    Abstract: A polycarbonate having high transparency, a high refractive index, low birefringence, moldability and moist heat resistance and an optical member comprising the same. The polycarbonate comprises 98 to 2 mol % of a unit represented by the following formula (I) and 2 to 98 mol % of a unit represented by the following formula (II) and has a specific viscosity measured at 20° C. of a solution prepared by dissolving 0.7 g of the polycarbonate in 100 ml of methylene chloride of 0.12 to 0.40. In the formula (I), R1 to R8 are each independently a hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, alkyl group having 1 to 6 carbon atoms, aryl group having 6 to 12 carbon atoms, alkenyl group having 2 to 6 carbon atoms, alkoxy group having 1 to 6 carbon atoms or aralkyl group having 7 to 17 carbon atoms. In the formula (II), R9 to R12 are each independently a hydrogen atom, hydrocarbon group which may contain an aromatic group having 1 to 9 carbon atoms, or halogen atom, X is an alkylene group, and “n” is an integer of 0 to 3.
