Abstract: A liquid crystal display device includes a liquid crystal panel and a light guide plate below the liquid crystal panel. The liquid crystal display device also includes first and second LED packages that are arranged alternately along a light entering surface of the light guide plate. Additionally, the liquid crystal display device includes a printed circuit board that has first and second portions facing each other and at which the first and second LED packages are mounted, respectively. The printed circuit board also includes a third portion, in a bent state, which connects an end of the first portion in a lengthwise direction, and an end of the second portion in a lengthwise direction. The liquid crystal display device further includes a first guide portion that is located at an outer side of the first and second LED packages. The first guide portion is interposed between and attached to the first and second portions.
