wherein an adhesive layer having a lower adhesive force than that of the second bonding layer is arranged outside a region in which the second bonding layer is arranged, between the lower surface and the frame.

2. The liquid crystal display device according to claim 1 ,

wherein the second bonding layer is arranged at a position overlapping the first bonding layer.

3. The liquid crystal display device according to claim 1 ,

wherein a light-emitting element is accommodated in the interior of one side of the frame.
