Thermoplastic resin composition

A thermoplastic resin composition comprising:

• a base resin comprising a polyarylene oxide-based polymer at 100 parts by weight;
• and
• an additive comprising one or more selected from the group consisting of compounds represented by Chemical Formula 1-1 to Chemical Formula 1-3 below at 0.1 to 5 parts by weight:
• In Chemical Formula 1-1,
• L1 and L2 each independently are a direct bond, a divalent heteroatom, a substituted or unsubstituted C3 to C10 cyclic alkylene group, or a substituted or unsubstituted C6 to C20 arylene group, and
• R1 and R2 each independently are hydrogen, a halogen group, a hydroxyl group, a cyano group, a nitro group, a substituted or unsubstituted C1 to C10 linear alkyl group, a substituted or unsubstituted C3 to C10 cyclic alkyl group, or a substituted or unsubstituted C6 to C20 aryl group.
• In Chemical Formula 1-2,
• L3 and L4 each independently are a direct bond, a divalent heteroatom, a substituted or unsubstituted C3 to C10 cyclic alkylene group, or a substituted or unsubstituted C6 to C20 arylene group, and
• R3 and R4 each independently are hydrogen, a halogen group, a hydroxyl group, a cyano group, a nitro group, a substituted or unsubstituted C1 to C10 linear alkyl group, a substituted or unsubstituted C3 to C10 cyclic alkyl group, or a substituted or unsubstituted C6 to C20 aryl group.
• In Chemical Formula 1-3,
• L5 and L6 each independently are a direct bond, a substituted or unsubstituted C3 to C10 cyclic alkylene group, or a substituted or unsubstituted C6 to C20 arylene group, provided that L5 and L6 are not both direct bonds.
