Description

Bonding Device The present invention relates to a bonding device. Electronic devices that provide video to a user, such as smartphones, digital cameras, laptop computers, navigation systems, and smart televisions, include a display device for displaying video. The display device generates video and provides it to the user through a display screen. With the recent technological advancement of display devices, various types of display devices are being developed. For example, display devices capable of displaying images not only on the front but also on the rear and sides are being developed. The display device includes a display panel for displaying images and a window placed on the display panel to protect the display panel. The window can be bonded to the upper surface of the display panel by a bonding device.
