Abstract
A liquid crystal panel of a scanning antenna includes a TFT substrate provided with a first dielectric substrate, a TFT supported by the first dielectric substrate, a gate bus line, a source bus line, and a patch electrode; a slot substrate provided with a second dielectric substrate, and a slot electrode that is formed on a first main surface of the second dielectric substrate and includes a slot arranged so as to correspond to the patch electrode; and a liquid crystal layer provided between the TFT substrate and the slot substrate. One of the TFT substrate and the slot substrate includes a projecting layer formed of resin and disposed on the liquid crystal layer side of the patch electrode or the slot electrode in a region surrounded by a sealing portion. The projecting layer is arranged so as not to overlap the patch electrode or the slot.
