<P>PROBLEM TO BE SOLVED: To provide an optical device which eliminates a lamp image by equalizing and projecting incident light from a plurality of light sources and further does not curve owing to heat generated by the light sources even when the light sources and optical device or optical equalization device are at a shorter distance, and to provide the optical equalization device, an optical sheet, a back light unit and a display device. <P>SOLUTION: The display device 70 is constituted by arranging a light deflecting element 28 of the optical device comprising a light propagation layer 23 and the light deflecting element or the optical equalization device 25 having a diffusion base 26 united on a light emission surface side of the light propagation layer of the optical device on a light source side of the display device, and further arranging an optical member 2 etc., on the light propagation layer of the optical device or the diffusion base of the optical equalization device when necessary. <P>COPYRIGHT: (C)2010,JPO&INPIT |
