Abstract: A secondary battery includes an electrode assembly having a positive electrode provided with a positive electrode tab, a separator, and a negative electrode provided with a negative electrode tab, the positive electrode, the separator, and the negative electrode being wound, the electrode assembly having a core part at a center thereof; a can configured to receive the electrode assembly therein, the negative electrode tab being connected to the can; a cap assembly coupled to an opening of the can, the positive electrode tab being connected to the cap assembly; and a reinforcing member provided on an end of the separator exposed beyond the positive electrode or the negative electrode to prevent heat of the positive electrode tab or the negative electrode tab from being transferred to the separator.

Abstract: A backlight unit may be provided which is capable of local dimming. The backlight unit includes: one or a plurality of light emitting devices; and a light guide plate including a top surface and a bottom surface, one or a plurality of grooves which are formed in the bottom surface and in which the light emitting device is disposed, a reflective layer which is disposed within the one or the plurality of grooves and reflects light emitted from the light emitting device, and a plurality of inverse prism patterns disposed in the top surface.
