<P>PROBLEM TO BE SOLVED: To provide a structure which allows the easy removal of a light guide plate from a mold, and makes it difficult for a stress or the like to influence the fine structure of a light incident portion of the light guide plate in a backlight which arranges light emitting diodes on a side surface of light guide plate. <P>SOLUTION: In the liquid crystal display device having the backlight which radiates light to a liquid crystal panel, LEDs which constitute a light emitting element are mounted on a light guide plate 120 which is mounted on the backlight, and edge portions of the light guide plate are tapered such that a width of the light guide plate is increased in the removal direction of the side surface of the light guide plate. Further, an ejector-pin 228 mark is formed on a lower surface of the light guide plate by pushing the ejector pin 228 in the removal direction of the light guide plate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
