Claim 0:
1. An electrode structure, comprising:
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,
wherein 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;
a second dielectric layer that includes a dielectric material having a refractive index higher than that of the first dielectric layer, wherein
the first dielectric layer is between the second dielectric layer and the plurality of pixel electrodes, and
the second dielectric layer has a slit at a position overlapping space between adjacent pixel electrodes of the plurality of pixel electrodes when viewed from the first direction; and

a third dielectric layer in at least a part of the slit, wherein
the third dielectric layer is in direct contact with the first dielectric layer, and
the third dielectric layer includes a dielectric material having a refractive index lower than that of the second dielectric layer.
