Abstract :In the present paper our aim is to investigate lightlike hypersurfaces of $\mathbb{R}^4_1$ having degenerate or non-degenerate planar normal sections. Firstly, we prove that as lightlike hypersurfaces in $\mathbb{R}^4_1$ always has degenerate planar normal sections. Then we examine the conditions for lightlike hypersurfaces in $\mathbb{R}^4_1$ to have non-degenerate planar normal sections and obtain some characterizations for such lightlike hypersurfaces.
Keywords : Lightlike hypersurface, non degenerate planar normal section, degenerate normal section
