It is an object of the present invention to provide a photosensitive transparent resin comprising a polyimide and a filler. Polyimine has the structure of formula 1: Wherein m and n are each independently from 1 to 600; X is a tetravalent organic group having a main chain moiety containing an alicyclic group; Y is a divalent organic group having a main chain moiety containing a oxoalkyl group Z is a divalent organic group having a branched moiety containing at least a phenol group or a carboxyl group. The filler includes at least one of alumina, graphene, inorganic clay, mica powder, cerium oxide, aluminum oxide, zinc oxide, zirconium oxide, carbon nanotubes, and nano carbon fibers. The filler is contained in an amount of 10 to 50% by weight based on the total weight of the photosensitive transparent resin. The photosensitive transparent resin has a transmittance of more than 90% at a wavelength of 400 to 700 nm and a color difference b value of less than 2. |
