Abstract
A liquid crystal panel for forming an aperture for an incident light includes guest-host liquid crystals, and includes first and second cells arranged such that one cell surface of them are in contact with each other. The liquid crystals of the first cell can be oriented in a first direction vertical to a direction of an optical axis of the panel or the direction of the optical axis. The liquid crystals of the second cell can be oriented in a second direction vertical to both the direction of the optical axis and the first direction or the direction of the optical axis. In the panel, the orientation direction of the liquid crystals at each region is controlled by an electric field, to form an aperture with high contrast for range imaging and an aperture with high light transmissivity for general imaging.
