Abstract: To reduce the size, simplify the structure of a light emitting and receiving system. The system that detects a target object with the use of reflected lights gained from a light irradiated to the target object includes a flat-plate shaped light control apparatus having light control parts, a light-entry apparatus allowing light to enter into a light control part, a light-receiving apparatus that receives emitting lights from the remaining light control parts, a control apparatus that controls the light-entry apparatus and the light-receiving apparatus and detects the target object. The light control apparatus includes liquid crystal elements supporting light control parts between a pair of substrates and a drive unit to drive the liquid crystal elements. Each of the light control parts includes a pair of electrodes, a high-resistance film disposed between the electrodes, and a liquid crystal layer disposed at least to the region overlapping the high-resistance film.

Abstract: To provide a liquid crystal element with a high contrast ratio capable of achieving both optical control that utilizes a memory property and optical control capable of supporting moving image displays. The two substrates are disposed with an angle formed by the respective orientation processing directions from 0° to less than 40°. The liquid crystal layer includes chiral material capable of generating a second orientation state that includes a twist different from that of the first orientation state in the liquid crystal molecules of the layer. The liquid crystal layer transitions from the second orientation state to the first orientation state and vice versa by the application of an electric field, and returns to the second orientation state when an electric field is applied in the second orientation state, thereby generating an orientation change in accordance with the size of the electric field, and the electric field is subsequently released.
