To provide a producing device which permits producing a panel molding by joining both panel constituents each other after plural panel constituents are positioned by using an alignment mark.

A frame stage 5 of a stationary type which is supported by a support and a panel stage 9 which is made movable vertically via a linear movement guiding mechanism 8 and is made movable in the three directions of vertical, transverse and peripheral directions in the plane direction by means of a table for positioning are disposed. The panel stage 9 penetrates an opening part 51 of the frame stage 5 and the upper surface thereof is set as a preset position so as to become higher than the upper surface of the frame stage 5. On the preset position, a liquid crystal panel 30 and a frame 40 are held on the stage and, thereafter, the panel stage 9 is lowered to the alignment position, is positioned, then, is furthermore lowered to a joining position and is joined (is stuck) with a double coated tape.
