<P>PROBLEM TO BE SOLVED: To provide an optical unit and optical elements in which the optical elements are mounted on a comparatively thin shaped light guide plate wherein an optical flux from a light source can be guided efficiently. <P>SOLUTION: By means that adhesive BD is made to stay in a notch 11k installed at an intersection part of an incident face 11a and an emitting face 11b, an LED light source 20 can be arranged at the optimum position against the incident face 11a. In addition, by means that the adhesive BD is made to stay at the end face 11m installed at the intersection part of the emitting face 11b and the slope 11c, it is made possible to increase the amount of light to be guided to the light guide plate 12 by suppressing infiltration of the adhesive BD. <P>COPYRIGHT: (C)2012,JPO&INPIT |
