Provided are a display device and a board supporting structure. The board supporting structure includes: a board; a main frame to which the board is fixed; a receiving portion formed at the main frame and on which the board is placed; and a connection member being a separate component fixing the board to the main frame and including a first portion coupled to the main frame and a second portion coupled to the board. Accordingly, an increase in thickness of the display device due to installation of the board is reduced, the performance reliability of the board is improved, the installation of the board is facilitated, and damage to the board is prevented.
