The frame gum is arranged between the first substrate and the second substrate; wherein the first substrate, the second substrate and the frame gum are bent into at least an arc structure. The gap is disposed on the first substrate and between the first substrate and the second substrate. The distance between the gap closed to the top of the arc structure and the second substrate is shorter than the distance between the gap far away from the top of the arc structure and the second substrate before the display board is bent into an arc structure. The liquid crystal layer is positioned between the first substrate and the second substrate, wherein the gap and the liquid crystal layer are wound by the frame gum. The invention maintains the size of the liquid crystal space by regulating the distance of the gap and the opposite substrate.
