Abstract: PROBLEM TO BE SOLVED: To provide a frame of a flat panel display device, which can be manufactured by a small-sized molding machine, a press, or the like without preparing many molds.
SOLUTION: A liquid crystal display device is manufactured by fitting a back light part 12 and a liquid crystal panel 11 having a light shielding double-sided adhesive tape stuck on an outer circumferential part thereof in order. The frame 13 comprises four corner frame members 132a and 132d which have recessed parts having a prescribed shape formed in both end parts and four side frame members 131a and 131d which have projecting parts, which have such shape that they can be fitted to the recessed parts, formed in both end parts. The frame 13 is manufactured by fitting the projecting parts into the recessed parts respectively. Since this configuration allows the corner frame members to be small and allows the side frame members 131a to 131d to be slender, the frame can be manufactured by the small-sized molding machine or the like by using a mold having these members properly arranged therein.
