The multifunctional glass window comprises an inner glass panel and an outer glass panel spaced from the inner glass panel. A sealing fixing piece is arranged between the inner glass panel and the outer glass panel. A sealed cavity is formed between the inner glass panel and the outer glass panel. A plurality of light permeable substrates are arranged in the sealed cavity. A spacing strip is connected between every two light permeable substrates, so that a plurality of independent air cells are formed. Each spacing strip is internally provided with a silica gel moisture absorbent. A shutter is arranged in the outer glass panel. The inner glass panel is provided with a switch for controlling the shutter to be folded and unfolded. A plurality of supporting frames are arranged in the sealed cavity, and every two supporting frames are crossed. The surfaces of the supporting frames are coated with fluorescent powder. Compared with the prior art, the multifunctional glass window can improve the living comfort of people by controlling the shutter to be folded or unfolded so as to expose or shield sunlight.
