Frame structure, backlight module and display

The utility model provides a frame structure which defines a first direction and comprises a first frame internally provided with at least one air exhaust channel, an attaching layer provided with at least one through hole and a second frame combined with the first frame through the attaching layer, and the first frame and the second frame jointly define a containing space extending in the first direction. The air exhaust channel is communicated with the containing space and the outside, the attaching layer is located in the containing space and divides the containing space into a first air exhaust channel and a second air exhaust channel which are communicated through the through hole, and residual air in the containing space can be led out from the air exhaust channel to the outside, so that the attaching area and the attaching integrity of the attaching layer are increased by reducing the residual air. Therefore, the bonding strength between the first frame and the second frame is improved, and the stabili
