Abstract
Provided is a liquid crystal display device capable of switching between a transparent state and a scattering state, reducing or preventing a decrease in transmittance in the transparent state, and reducing or preventing a decrease in luminance in the panel central portion in the scattering state. The liquid crystal display device includes, sequentially from its viewing surface side toward its back surface side: a first liquid crystal panel; a light source; and a second liquid crystal panel, the first liquid crystal panel including a polymer dispersed liquid crystal containing a polymer network and liquid crystal components, the light source being configured to irradiate a back surface side main surface of the first liquid crystal panel with light from an oblique direction.
