A structure for preventing vacuum suction when packing liquid crystal panels is disclosed. The structure includes a spaced buffer layer arranged between two liquid crystal panels, a first vacuum breaker structure arranged on a first surface of the spaced buffer layer to form at least one air gap between one of the liquid crystal panel and the spaced buffer layer, and the first surface is opposite to one of the liquid crystal panels. The vacuum suction between the liquid crystal panels and the spaced buffer layer is avoided by arranging the vacuum breaker structures therebetween. As such, the liquid crystal panel is prevented from being brought up by other liquid crystal panel due to the vacuum suction, which avoids the fragment and related cost.
