|1. (WO2018180964) LIQUID CRYSTAL CELL AND SCANNING ANTENNA|
|Applicants:||SHARP KABUSHIKI KAISHA
|Title:||LIQUID CRYSTAL CELL AND SCANNING ANTENNA|
This liquid crystal cell C is a liquid crystal cell in which a plurality of antenna units U are arrayed, wherein the liquid crystal cell C is provided with: a TFT substrate 101 that includes a first dielectric substrate 1, a plurality of TFTs 10 and a plurality of patch electrodes 15 electrically connected to the TFTs 10; a slot substrate 201 that includes a second dielectric substrate 51 and slot electrodes 55 that include a plurality of slots 57; and a liquid crystal layer LC which is sandwiched between the TFT substrate 101 and the slot substrate 201 and in which the patch electrodes 15 and the slot electrodes 55 are disposed so as to face each other. When a voltage is not impressed between the patch electrodes 15 and the slot electrodes 55, liquid crystal molecules that constitute the liquid crystal layer LC are oriented in all orientation angle directions.
