Abstract

A display apparatus includes a base part, a main body, a slider connected to the main body, a guide rail to stand on the base part, and to guide the slider to slide thereon to move the main body up and down. The display apparatus also includes at least one spiral spring having an elasticity enough to support weight of the main body to extend and contract in response to a movement of the slider. Accordingly, the display apparatus has an improved structure of conveniently adjusting a position of the main body due to the slider being slid smoothly along the guide bracket.
