WIPO Patent Application WO/2018/030180
Kind Code:

Abstract:
A liquid crystal panel (100A) of a scanned antenna comprises: a TFT substrate (101A) including a first dielectric substrate (1), a TFT supported by the first dielectric substrate (1), a gate bus line, a source bus line, and a patch electrode (15); a slot substrate (201A) including a second dielectric substrate (51), and a slot electrode (55) that is formed on a first principal surface of the second dielectric substrate (51) and has a slot (57) arranged so as to correspond to the patch electrode (15); and a liquid crystal layer (LC) provided between the TFT substrate (101A) and the slot substrate (201A). One of the TFT substrate and the slot substrate has a resin-made projecting layer (44a) more toward the liquid crystal layer (LC) side than the patch electrode (15) or the slot electrode (55) within a region surrounded by a seal part. The projecting layer (44a) is arranged so as not to overlap either the patch electrode (15) or the slot (57).
