摘要： A TFT substrate includes a dielectric substrate and a plurality of antenna unit regions arranged on the dielectric substrate. Each of the plurality of antenna unit regions has a TFT and a patch electrode electrically connected to the drain electrode of the TFT. The patch electrode includes a first electrode layer formed of the same conductive film as the gate electrode of the TFT and a second electrode layer formed of the same conductive film as the source electrode of the TFT.

摘要： A liquid crystal device includes a first substrate (TFT substrate) including a first dielectric substrate, a second substrate (slot substrate) including a second dielectric substrate, a liquid crystal layer provided between the first substrate and the second substrate and in all of an effective region and a portion of a non-effective region, a sealing seal portion configured to define the maximum value of the area of the liquid crystal layer when viewed from a normal direction of the first or second dielectric substrate, a cell gap control seal portion configured to define the minimum value of the thickness of the liquid crystal layer in the effective region, and a buffer portion provided in contact with the liquid crystal layer in the non-effective region and that deforms more easily due to external force than the first and second dielectric substrates in the effective region. The buffer portion includes a sheet and a joining section that joins the sheet and the first or second dielectric substrate. The sheet deforms more easily due to external force than the first and second dielectric substrates in the effective region, and/or at least a portion of the joining section deforms more easily due to external force than the cell gap control seal portion.
