Polarizing plate, display, and electronic apparatus
View Patent ↗The present invention provides a polarizing plate including: a layer of polarizer for polarizing incident light and emitting the polarized light; and a coating type optically anisotropic layer disposed on the side to which the polarized light is emitted from the polarizer layer.
1. A display comprising:
an organic electroluminescence panel including a plurality of organic electroluminescence elements that generate light; and
a circularly polarizing plate on a display surface side of the panel through which the light is output, the circularly polarizing plate comprising
a polarizer layer that circularly polarizes incident light and emits the circularly polarized light from one side thereof,
an optically anisotropic layer on the side to which the circularly polarized light is emitted from the polarizer layer, and
a molecule fixing layer which is a film in contact with the optically anisotropic layer and that controls an order parameter of the optically anisotropic layer so that orientations of molecules constituting the optically anisotropic layer are fixed in a random state or in an intermediate state between the random state and an aligned state.
2. The display according to claim 1 , wherein the circularly polarizing plate comprises:
a first base layer;
the polarizer layer disposed over the first base layer;
a second base layer disposed over the polarizer layer;
the molecule fixing layer disposed over the second base layer;
the optically anisotropic layer disposed over the molecule fixing layer; and
a protective layer disposed over the optically anisotropic layer.
3. The display to according claim 1 , wherein the circularly polarizing plate comprises:
a first baser layer;
the polarizer layer disposed over the first base layer;
the optically anisotropic layer disposed over the polarizer layer;
the molecule fixing layer disposed over the optically anisotropic layer; and
a second base layer disposed over the molecule fixing layer.
4. The display according to claim 1 , wherein retardation represented by the product of the double refractive index of the molecules in the optically anisotropic layer and the thickness of the optically anisotropic layer is in the range of 100 to 200 nm or in a range of an odd number times the range.
