• Null Cartan curve
• ruled null surface
• principal normal indicatrix

In this paper, we consider the null surfaces of null Cartan curves in Anti-de Sitter 3-space and making use of singularity theory, we classify the singularities of the null surfaces and investigate the relationships between singularities of the null surfaces and differential geometric invariants of null Cartan curves in Anti-de Sitter 3-space. Finally, we give an example to illustrate our results.
