Patent Images
1. A reflective magnetic display comprising:
- a magnetic material layer region formed between front and rear substrates, wherein the magnetic material layer region comprises magnetic particles that reflect incident light when magnetic moments are randomly oriented and that reflect or transmit the incident light, in accordance with polarization of the incident light, when the magnetic moments are aligned in one direction;
an electrode that applies a magnetic field inducing a magnetic moment alignment on the magnetic material layer region in accordance with electrical operation; and
a polarizer that is disposed on the front substrate and has a polarization transmission axis in parallel with the magnetic moments of the magnetic material layer region when the magnetic moments are aligned in the one direction.
