Abstract: An electrode structure includes: a plurality of pixel electrodes arranged separately from each other; and a plurality of dielectric layers laminated in a first direction with respect to the plurality of pixel electrodes, in which the plurality of dielectric layers includes: a first dielectric layer that spreads over the plurality of pixel electrodes in a direction intersecting with the first direction; and a second dielectric layer that includes dielectric material having a refractive index higher than that of the first dielectric layer, sandwiches the first dielectric layer together with the plurality of pixel electrodes, and has a slit at a position overlapping space between pixel electrodes adjacent when viewed from the first direction.

Abstract: A message input unit inputs a message. A message memory stores the message. An information extraction rule memory stores a plurality of information extraction rules. An information extraction decision unit decides whether at least one of the plurality of information extraction rules is applicable to the message at a decision timing. An information extraction unit extracts information from the message using at least one information extraction rule when the at least one information extraction rule is applicable to the message.
