1. A thermoplastic resin composition comprising:
about 45 wt % to about 65 wt % of an aromatic polyamide resin comprising a repeat unit represented by Formula 1, a repeat unit represented by Formula 2, and/or a repeat unit represented by Formula 3;
about 1 wt % to about 20 wt % of an olefin copolymer;
about 15 wt % to about 35 wt % of calcium carbonate; and
about 5 wt % to about 25 wt % of zinc oxide,
wherein the calcium carbonate and the zinc oxide are present in a weight ratio (calcium carbonate:zinc oxide) of about 5:1 to about 1:1,

OG Complex Work Unit Chemistry
wherein R1 and R3 are each independently a C1 to C6 hydrocarbon group or a halogen atom, R2, R4, and R5 are each independently a C6 to C12 linear or branched alkylene group, and n1 and n2 are each independently an integer of 0 to 4, and
