Abstract
Provided is a liquid crystal display element capable of switching between a transparent state and a scattering state and of reducing or preventing a decrease in luminance in the scattering state. The liquid crystal display element includes a liquid crystal panel containing a polymer-dispersed liquid crystal containing a polymer network and a liquid crystal component, and a light source module including a light source adjacent to the liquid crystal panel and a mirror configured to reflect light emitted from the light source toward the liquid crystal panel.

A liquid crystal display element comprising:
- a liquid crystal panel containing a polymer-dispersed liquid crystal including a polymer network and a liquid crystal component;
- and
- a light source module comprising a light source adjacent to the liquid crystal panel and a mirror configured to reflect light emitted from the light source toward the liquid crystal panel,
- the mirror comprising a collimator configured to collimate a Lambertian light source, a first light distributor, and a second light distributor,
- a thickness direction, an in-plane horizontal direction, and an in-plane vertical direction of the liquid crystal panel corresponding, respectively, to an x-axis direction, a y-axis direction, and a z-axis direction,
- the collimator being away from the liquid crystal panel in the z-axis direction,
- the first light distributor being further away from the liquid crystal panel than the collimator in the x-axis direction, and
- the second light distributor being further away from the liquid crystal panel than the first light distributor in the x-axis direction.
