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 disposable diaper includes a topsheet, a backsheet and an absorbent core therebetween. The topsheet is composed of a central sheet covering the core and a pair of side sheets lying at transversely opposite sides of the central sheet and extending longitudinally of the diaper, together with the backsheet. Each side sheet has a proximal zone bonded to the backsheet without overlapping a side edge of the central sheet bonded to the backsheet. An outer zone bonded to the remaining zone of the backsheet lying outside the proximal zone forms an elasticized first side flap and an inner zone extending above the central zone forms an elasticized second side flap.

Abstract: A disposable diaper includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core therebetween. A pair of contractible leg-gasket cuffs extend outward beyond transversely opposite side edges of the absorbent core and a pair of contractible barrier cuffs extend adjacent the side edges of the absorbent core and are biased to rise from an upper surface of the top sheet above the absorbent core. Each of the barrier cuffs is made of a nonwoven fabric and each of the leg-gasket cuffs is formed with a portion of the nonwoven fabric extending outward and a portion of the backsheet extending outward beyond the side edge of the absorbent core and bonded onto the extending portion of the nonwoven fabric. A reinforcing sheet is bonded to an upper surface of each of the leg-gasket cuffs along its outer side edge in order to enhance a tensile strength of the leg-gasket cuff. The reinforcing sheet is made of a nonwoven fabric.
