Claim 0:
1. A polycarbonate resin composition, comprising:
(a) a linear polycarbonate resin including a repeating unit of the following Chemical Formula 1;
(b) a branched polycarbonate resin including a repeating unit of the following Chemical Formula 1;
(c) 0.04 parts by weight to 0.15 parts by weight of a fluorinated sulfonate-based metal salt;
(d) 1.5 parts by weight to 5.0 parts by weight of a phenyl methyl silicone oil having a kinematic viscosity of 5 mm2/sec to 40 mm2/sec at 25° C.; and
(e) 0.05 parts by weight to 0.2 parts by weight of a phenyl methyl silicone resin,

R1 to R4 are each independently hydrogen, C1-10 alkyl, C1-10 alkoxy, or halogen; and
Z is C1-10 alkylene unsubstituted or substituted with phenyl, C3-15 cycloalkylene unsubstituted or substituted with C1-10 alkyl, O, S, SO, SO2, or CO,, wherein in Chemical Formula 3:
R5 and R6 are each independently C1-10 alkyl, C1-10 alkenyl, or C6-10 aryl;
R7 is phenyl;
n is an integer from 0 to 10; and
m is an integer from 1 to 10.
