Abstract
A liquid crystal display device includes a liquid crystal layer, a row signal line, a column signal line, and a magnetic memory element, the row signal line and the column signal line being formed on one side or opposing sides of the liquid crystal layer. Magnetization of the magnetic memory element is controlled by a magnetic field generated by at least one of the row signal line and the column signal line to be in one of a magnetized state and a non-magnetized state, and a moment for driving the liquid crystal layer is generated by the magnetic memory element being retained in the magnetized state, thereby causing optical modulation in the liquid crystal layer.
