The display device contains a base and a display unit. The display unit contains a backlight source configured to an edge portion of the display unit. The edge portion of the display unit is plugged into the base. The present invention integrates a base with the display unit so that a thicker backlight source is concealed in the base whereas the portion of the display unit that is exposed outside the base can have an ultra-thin structure, thereby achieving the superior appearance and still conforming to the ultra-thin design trend.
