The invention relates to a window capable of being opened in three dimensions, including a window frame and window plates sealing the space enclosed by the window frame. The window frame is enclosed by a left vertical baffle plate, an upper transverse baffle plate, a right vertical baffle plate and a lower transverse baffle plate. The window frame is further provided with a middle vertical baffleplate which divides the window frame into two window holes distributed in the left-right direction. One window plate is arranged in each window hole. A transverse rotating shaft is arranged right in the middle of each window plate. One end of each transverse rotating shaft is rotationally connected to a vertical shaft rotationally installed on the middle vertical baffle plate, and the other end isrotationally connected to a connecting block. Each connecting block is connected with the window frame through a horizontal telescopic rod for driving the corresponding window plate to rotate aroundthe vertical shaft. A window rotating mechanism for driving the corresponding window plate to rotate around the corresponding transverse rotating shaft is arranged between each connecting block and the corresponding transverse rotating shaft. The invention provides a window capable of being opened in three dimensions which can guide the outdoor wind to the indoor, and thus, the problem that the existing window cannot actively guide the wind to the indoor for ventilation according to the flow direction of the outdoor wind is solved.
