<P>PROBLEM TO BE SOLVED: To provide an optical module capable of adjusting an illuminance distribution without using a light guide plate. <P>SOLUTION: The optical module 20 has a deflection optical sheet 50 including one edge part 50c1 facing one direction d1 and the other edge part 50c2, a reflection plate 21 having a reflection face 22 facing the deflection optical sheet, and a light source 25 for irradiating light to a region between the deflection optical sheet and the reflection plate from the one edge part side to the other edge part side in the one direction. The deflection optical sheet includes a body 55 and a plurality of unit optical elements 60 arranged on the body. A distance sd from the reflection face 22 of the reflection plate 20 up to a face 55b on the opposite side facing the reflection face of the body 55 of the deflection optical sheet becomes smaller from the one edge part side to the other edge part side in the one direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
