To provide a technique for preventing water from entering from an opening in a display device including the opening for exhaust.

An exhaust unit 30 includes inclines 12 having three steps inclined down toward the rear and an opening 11 provided between the two inclines 12. Further, a groove 13 extended to the right and left is formed at nearly the center in a longitudinal direction of the inclines 12, to prevent water 50 from easily entering the inside via the opening 11. A groove lower end 13a of the groove 13 is formed at the highest position in the center, and a groove side end 13b is formed at the lowest position to discharge water 50 in the groove 13 from the groove side end 13b.
