Let $mathcal{L}$ be a bounded lattice. The essential element graph of $mathcal{L}$ is a simple undirected graph $varepsilon_{mathcal{L}}$ such that the elements $x,y$ of $mathcal{L}$ form an edge in $varepsilon_{mathcal{L}}$, whenever $x vee y $ is an essential element of $mathcal{L}$. In this paper, we study properties of the essential elements of lattices and essential element graphs. We study the lattices whose zero-divisor graphs and incomparability graphs are isomorphic to its essential element graphs. Moreover, the line essential element graphs are investigated.
