A display includes a frame, a liquid crystal panel device, a flat light source device, a bracket structure, and a driving circuit board. The liquid crystal panel device and the flat light source device are disposed on the frame. The flat light source device has an illuminant surface toward the liquid crystal panel device. A first airway is formed between the flat light source and the liquid crystal panel device. The driving circuit board is fixed on the bracket structure and electrically connected with the liquid crystal panel device. A gap is formed between the driving circuit board and the flat light source to be an outlet of the first airway. The surface of the driving circuit board and the illuminant surface form an included angle, and the included angle is greater than or equal to 5 degrees and less than or equal to 135 degrees.
