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 vehicle lamp device in which the gap provided beside the headlamps is made inconspicuous, and rainwater or dust are prevented from entering the gap. The inventive vehicle lamp device in one embodiment includes a unit movable rectangular headlamp and a rectangular vehicle lamp arranged with a gap therebetween, and, of the confronting side walls of the front lens of at least one of the lamps, at least one has a front edge protruding outwardly so that the gap between the front lenses of the lamps is narrower at the front edge of the side wall.

Abstract: A headlight device of the type including a lamp body formed of a synthetic resin material, a lens covering the front surface of the lamp body, an electric bulb provided in a lamp space defined between the lamp body and the lens, and a clearance lamp provided adjacent to one side edge of the lamp body. The lamp body has a parabolic surface reflective mirror portion opening in the forward direction, and an auxiliary reflective mirror portion extending from the left or right side edge portion of the parabolic surface reflective mirror portion of the side of the clearance lamp. The auxiliary reflective mirror portion is generally inclined in the direction toward the distal edge of the lens, and has a concave inner surface. The lens has a front surface portion, and at least one side wall portion extending in the rear direction from the side edge of the front surface portion adjacent to the clearance lamp.
