표시광고에 대한 민사법적 규율의 요건 — 잘못된 정보를 제공하는 표시광고행위의 ‘위법성’을 중심으로 —

This article seeks to emphasize the importance of a requirement 'illegality' when claiming for damages and rescission of contract based on wrong labelling and advertisement and set more specific standards for this requirement. To achieve this goal, firstly I argued that the requirement is material and has became more important nowadays. And then I analyzed a statute "Fair Labelling and Advertising Act" which provide a general regulation on labelling and advertisement to specify this requirement. Further I focused on that wrong labelling and advertisement should be regulated but certain exceptions should be condoned at the same time considering their functions, and suggested to subdivide the requirement into separate classifications, that is, 'importance of information' and the rest for the systematic regulation.
