A liquid crystal display device includes a display panel and a backlight module. The display panel includes a TFT substrate. The TFT substrate includes a base portion that is flat and an extending portion curvedly extending from a side of the base portion. A driving chip is positioned on the extending portion and electrically coupled to the TFT substrate. The backlight module includes a light guiding plate including a main portion that is flat and a bending portion curvedly extending from a side of the main portion. The main portion is laminated on a side of the base portion. The bending portion extends toward a direction away from the base portion. An end surface of the bending portion away from the main portion is a light-incident surface of the light guiding plate. A surface of the main portion facing and adjacent to the base portion is a light-emitting surface.
