Abstract:
An optical element comprising:a laminate including a reflective type polarizer for separating incident light into polarized light components through reflection and transmission, and a dichromatic polarizer laminated on said reflective type polarizer; wherein a variation of hue between two points calculated by an expression: {(x2âˆ’x1)2+(y2âˆ’y1)2} is not larger than 0.06 when x1 and y1 express a hue at a point with a predetermined elevation angle and any azimuth angle, and x2 and y2 express a hue at another point with the same elevation angle and a changed azimuth angle in a case where transmitted light is obliquely viewed in a condition that said laminate is disposed on a planar light source so that said reflective type polarizer is located in an inner side.
