    摘要： A rechargeable battery pack may include a battery cell configured to draw out an electrode tab from an electrode assembly accommodated in a pouch, a protection circuit module (PCM) connected to an electrode tab drawn out to a terrace of the pouch and connected to a printed circuit board (PCB) including a protection circuit through a flexible printed circuit board (FPCB). The rechargeable battery pack may include top tape configured to surround the protection circuit module and is attached to the battery cell to form a terrace space therein, and a flame retardant coated portion formed by coating a flame retardant coating agent on at least one portion of the protection circuit module exposed to an outside of the top tape.

    摘要： A polarizing plate includes: a polarizer; a pattern layer on one surface of the polarizer, the pattern layer including a first refractive index layer having at least one engraved pattern and a second refractive index layer having a filling pattern filling at least a portion of the engraved pattern, the first refractive index layer having a higher refractive index than the second refractive index layer; and a first protective layer. The polarizing plate has a structure in which the polarizer, the second refractive index layer, the first refractive index layer and the first protective layer are sequentially stacked in that order, or in which the polarizer, the first protective layer, the second refractive index layer and the first refractive index layer are sequentially stacked in that order. The first protective layer includes a base film including at least one resin of triacetylcellulose, polyethylene terephthalate, cyclic olefin polymer, and acrylic resins.
