Abstract: A lighting device includes a light guide plate configured to guide and diffuse a light from a light source, and a garnish body including a lighting area to which the diffused light is radiated, wherein the light guide plate is disposed at a predetermined angle with respect to the garnish body.

Abstract: Disclosed are an electrolytic solution for lithium secondary batteries capable of improving lifespan characteristics of a lithium secondary battery under a high voltage condition and a lithium secondary battery including the same. The electrolytic solution may includes a lithium salt, a solvent, and a functional additive. In particular, the functional additive includes a high-voltage additive including a first high-voltage additive, e.g., hexafluoroglutaric anhydride, and a second high-voltage additive, e.g., fluoroethylene carbonate.
