According to an example, the vent line 550 may include first to fourth vent lines 551 to 554 . For example, both ends of the first vent line 551 may be respectively connected to the first and second vertical partitions 531 and 532 . In addition, one end of the first vent line 551 extends to have a first inclination angle with respect to the first horizontal partition 511 , and the other end of the first vent line 551 has a second end with respect to the first horizontal partition 511 . It may be extended to have an inclination angle. Here, the first and second inclination angles may be the same as or different from each other according to the shape of the first vent line 551 . Accordingly, the first vent line 551 includes two straight parts, and a vent part may be formed at a point where the two straight parts meet. In addition, the vent part may be configured in a straight or curved shape, but is not limited to this shape. Accordingly, the first vent line 551 includes a vent portion vented toward the first sound generating module 210 , thereby preventing a decrease in sound pressure between the display panel 100 and the rear structure 300 .

According to an example, the inclination angle of the vent portion may vary according to the required amount of suppression of the standing wave, and the inclination angle of the vent portion may be set to vary from 10 degrees to 30 degrees. For example, the inclination angle of the vent portion may be formed to be large when the sound output region is for a low-pitched sound range or when the output of the vibration generating device 200 is large. In addition, the inclination angle of the vent may be formed small when the sound output region is for a high-pitched sound range or when the output of the vibration generating device 200 is small.

According to an example, the vent portion of the vent line 550 may reduce a decrease in sound pressure between the display panel 100 and the rear structure 300 . For example, sound waves generated by vibrating the display panel 100 by the vibration generating device 200 may propagate radially from the center of the vibration generating device 200 . This sound wave can be called a progressive wave. When the traveling wave reaches one side of the partition member 500 , it is reflected from one side of the partition member 500 to form a reflected wave that travels in the opposite direction to the traveling wave. In addition, the reflected wave may overlap or cancel the traveling wave to form a standing wave in which the sound wave does not proceed and is stagnated at a certain position. Such a standing wave may reduce the sound pressure, thereby deteriorating the sound output characteristics of the vibration generating device 200 . Accordingly, the partition member 500 may prevent a decrease in sound pressure due to the standing wave generated by the interference of the reflected wave and the traveling wave by forming the vent portion. In addition, the standing wave causing the sound pressure reduction occurs a lot at the point where the magnitude of the traveling wave and the reflected wave is large. Accordingly, the vent portion of the vent line 550 may be disposed at a position where the sound wave arriving from the sound generating module is greatest.
