Abstract

The present disclosure relates to a display device including a piezoelectric film type actuator, the display device having a structure in which a groove is provided in a rear surface of a metal layer for supporting and encapsulating a rear surface of a display panel, and the piezoelectric film type actuator is provided in the groove. Accordingly, the display device may reduce the total thickness and improve heat dissipation performance.

Description

technical field [0001] Disclosed herein is a display device for providing images, and more particularly, a display device for providing sound together with images without installing a separate speaker. Background technique [0002] The display device may include a display panel for providing images. The display panel may include a liquid crystal display panel, an organic light emitting diode display panel, a quantum dot display panel, a micro LED display panel, and the like. [0003] Such a display device may include a speaker for providing sound and a display panel. The speakers can be installed in the display unit or set up separately as a sound bar. When the speaker is installed in the display device, the speaker can generally be installed on each side surface of the display panel. [0004] When the speaker is installed in the display device, the propagation direction of the sound generated through the speaker may not be directed toward the viewer. For example, the so...
