Abstract

The present invention provides a display device that can efficiently guide the sound emitted by the sound generation unit towards the front of the display unit. [Solution] The display device (1) comprises a housing (11) on which a display unit (12) is provided, the housing having sound output holes (18L, 18R) below the display unit and on the front side of the display unit, a sound generating unit (21) housed inside the housing that emits sound, a first inclined surface (32) provided facing the sound generating unit and sound output holes and directing the sound emitted by the sound generating unit toward the sound output holes, and a second inclined surface (33) provided at a position further from the sound output holes than the first inclined surface and at an angle higher than the first inclined surface relative to the sound output holes, and directing the sound emitted by the sound generating unit toward the sound output holes.
