LLCs are not required to have a trade name. However, many choose to use one. A trade name is also known as a fictitious name or DBA (doing business as). This name is the one the company does business under if it does not use its actual or "legal" name. For example, if Jones Development LLC does business as Bruce Jones and Sons, then "Jones Development LLC" is the legal name and "Bruce Jones and Sons" is the trade name.
