PURPOSE: A structure for supporting a screen and a filter of a projection TV is provided to use a main bracket and an auxiliary bracket, so as to prevent the distortion of the screen and filter. CONSTITUTION: A cabinet(20) supports a screen and a filter(12). A support unit including a main bracket(40) and an auxiliary bracket(42) connects the screen and filter(12) to the cabinet(20), and is movable from the cabinet(20). The main bracket(40) includes a coupling slot(40a) formed in a diagonal direction at one side thereof, an insertion groove formed at the other side thereof, and compression protuberances(401) projected from the insertion groove diagonally each other. Also, the main bracket(40) is installed in the cabinet(20) movably in a diagonal direction as much as the length of the coupling slot(40a) through coupling screws(44) by perforating into the coupling slot(40a), and compresses and supports the edge of the screen and filter(12) inserted in the insertion groove using the compression protuberances(401). The auxiliary bracket(42) includes a coupling slot(42a) formed in a horizontal direction at one side thereof, an insertion groove formed at the other side thereof, and compression protuberances(421) projected from the insertion groove diagonally each other. Also, the auxiliary bracket(42) is installed in the cabinet(20) movably in a horizontal direction as much as the length of the coupling slot(42a) through the coupling screws(44) by perforating into the coupling slot(42a), and compresses and supports the side of the screen and filter(12) inserted in the insertion groove using the compression protuberances(421).
