    • An optical element of the invention comprises at least two laminated layers of at least one kind of reflective polarizer (a); and at least one layer of at least one kind of retardation layer (b) for changing polarization properties laminated between the reflective polarizers (a), the combination of the layers being designed so as to provide a incident-light transmittance depending on an incident angle of an incident light and designed such that a shielded light is not absorbed but reflected, wherein at least one layer of the reflective polarizer (a) is a circular polarization type reflective polarizer (a1) capable of transmitting a certain circularly polarized light and selectively reflecting an oppositely circularly polarized light; at least one layer of the reflective polarizer (a) is a linear polarization type reflective polarizer (a2) capable of transmitting one of perpendicular linearly polarized lights and selectively reflecting the other of the perpendicular linearly polarized lights; and the retardation layer (b) is a layer (b1) having a front (in the normal direction) retardation value of about λ/4 and having a retardation value of at least λ/8 with respect to an incident light inclined by at least 30° to the normal direction. The optical element can effectively shield transmitted lights with respect to obliquely incident lights and can control coloring.
    • 本发明的光学元件包括至少两种反射型偏振器(a)的至少两层叠层; 以及用于改变层叠在反射偏振器(a)之间的偏振特性的至少一种延迟层(b)的至少一层,所述层的组合被设计成根据入射角提供入射光透射率 被设计为使得屏蔽光不被吸收而被反射,其中反射偏振器(a)的至少一层是能够透射某种圆偏振光并选择性反射的圆偏振型反射偏振器(a1) 相反圆偏振光; 反射偏振器(a)的至少一层是能够透射垂直线偏振光中的一个并选择性地反射另一个垂直线偏振光的线偏振型反射偏振器(a2) 并且相位差层(b)是具有相对于至少倾斜的入射光的正面(法线方向)延迟值为大约λ/ 4并具有至少λ/ 8的延迟值的层(b1) 与正常方向30°。 光学元件可以有效地屏蔽相对于倾斜入射光的透射光并且可以控制着色。
