1. A positive photosensitive resin composition comprising:
100 parts by weight of a siloxane-based copolymer;
5 to 50 parts by weight of a 1,2 quinonediazide compound;
0.1 to 10 parts by weight of one or more kinds of UV absorbers represented by the following Chemical Formula 1; and
a solvent included in such an amount that the solid content of the total resin composition becomes 10 to 90 wt %,
wherein the siloxane-based copolymer contains an unreacted monomer content less than 10 wt % and a residual catalyst content less than 2,000 ppm:
