ABSTRACT:
Light-emitting elements can be accurately directly opposed to the entrance surface of a light guide at an accurate distance therefrom, and can be mounted on a single side of a printed circuit board together with other electronic components, whereby the number of manufacturing steps and the thickness of a liquid crystal display device can be reduced. The light guide and the printed circuit board are disposed on the back surface of the liquid crystal display panel, and the respective light-emitting elements are inserted through through-holes formed to extend through the printed circuit board, with the light-emitting portions of the respective light-emitting elements opposed to the entrance surface of the light guide. The light-emitting elements, together with the other electronic components, are mounted on the printed circuit board from one side. Electrodes of the light-emitting elements are bridged and secured to a mounting surface of the printed circuit board.
