A television cabinet includes a front board, a rear board, at least two active boards, two side boards, and a top board. Therein, the active boards are hinged between the front board and the rear board, while each active board comprises a first panel and a second panel hinged together for enabling the front board and the rear board to move between a folded position and an unfolded position. The side boards are slidingly disposed between the front board and the rear board at the unfolded position. The top board is combined to the front board, the rear board, and the two side boards as a plane on top at the unfolded position. Therefore, the cost and inconvenience of transportation are lowered.
