LIGHT SOURCE DEVICE, BACKLIGHT DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
A light source device having light guide elements (2a to 2f) and light emitting elements (3a to 3f) for supplying light to each of the light guide elements. The light guide elements each has a wedge-like shape whose thickness is reduced from one end to the other end. The light guide elements are tandem arranged such that the thinner end of a light guide element lies over the thicker end of the other light guide element. Each light guide element has holding sections recessed in the width direction (8a to 8f, 9a to 9f) in its thicker end on which the other light guide element lies. In the light guide device in which the wedge shaped light guide elements are tandem arranged, positional displacement between light guide elements is prevented.
