Abstract
The curved-type rigid board includes: a main sheet layer capable of maintaining a curved state with a certain curvature; a first adhesive layer formed on the main sheet layer; a sub sheet layer bonded onto the main sheet layer by the first adhesive layer while the sub sheet layer forms a line structure having diagonal lines, which do not match directions of horizontal and vertical lines of the mesh structure of the thermosetting resin of which the main sheet layer is made, in order for the main sheet layer to have rigidity to maintain the curved state; a second adhesive layer formed on the sub sheet layer; and a pattern forming layer bonded onto the sub sheet layer by the second adhesive layer.
