Abstract:
An image display device comprises: a display panel module (180); a housing (110) having a frame part and a rear part, the housing including a first opening and a second opening that allow an internal space surrounded by the frame part, the rear part, and the back of the display panel module (180) to communicate with the outside; a driver IC (124) for driving the display panel module (180); a fan (116) that allows air entering the internal space through the first opening to exit through the second opening; and a heat dissipation plate (130) thermally connected to the driver IC (124). The heat dissipation plate (130) is located between the first opening and the second opening in the internal space such that the heat dissipation plate (130) is arranged to form, in a first space of the internal space which contacts a first surface that is one surface of the heat dissipation plate (130), a first flow passage starting from the first opening and extending along the first surface and the surface of the frame part that faces the first space, and to form, in a space near a second surface that is the other surface of the heat dissipation plate (130), a second flow passage located downstream of the first flow passage and reaching the second opening.
