The present invention is characterized by including an aromatic vinyl-based copolymer, glass fiber, and zinc oxide, wherein the zinc oxide has an average particle size (D50) of about 0.5 to 3 μm as measured by a particle size analyzer, and a size ratio (B/A) of peak B, spanning the range of 450 to 600 nm, to peak A, spanning the range of 370 to 390 nm, of about 0.01 to 1.0 when measuring photoluminescence. The thermoplastic resin composition exhibits excellent rigidity, antibacterial properties, weather resistance, external appearance and the like.

An air conditioner and an air guide for an air conditioner are provided, the air guide being configured to guide air to a cross-flow fan of the air conditioner. The air conditioner may include a case including a front panel and a rear panel, the front panel including an intake grill and an outlet, a cross-flow fan and a heat exchanger being disposed inside of the case. The rear panel may include an air guide. The air guide may include a first guide surface inclined toward the cross-flow fan, and a second guide surface positioned at a downstream side of the first guide surface. The first guide surface may include at least one distribution guide that distributes and guides air, and thus, the air having been equally distributed by means of the at least one distribution guide may be suctioned into the cross-flow fan so that vortex generation is prevented, thereby enabling noise to be reduced.
