<P>PROBLEM TO BE SOLVED: To provide a light emission sheet without generating lamp images, of high light utilization efficiency, and emitting light with an excitation light source, and to provide a backlight unit using the as well as a display device. <P>SOLUTION: The light emission sheet 1 constitutes a light-emitting layer 7 and a first light control structure 5, sequentially from an incidence face side. The first light control structure 5 is provided with a plurality of convex first cylindrical lenses 61 aligned nearly parallel at a given pitch, and a plurality of convex second cylindrical lenses 62 aligned in a direction nearly orthogonal to the first cylindrical lenses 61. Light from the excitation light sources is absorbed at the light-emitting layer 7 to emit visible light, which is adjusted for light distribution by the first light control structure 5. <P>COPYRIGHT: (C)2011,JPO&INPIT |
