    Abstract: A glass device including a thin glass substrate which has a glass thickness of 300 μm or less is enabled to be provided more easily. In a method for manufacturing the glass device, one or more through holes are formed in a glass substrate, and a first wiring on a first surface side of the glass substrate and a second wiring on a second surface side of the glass substrate are electrically connected to each other via the through holes. After the first wiring is provided, the through holes are formed while the glass substrate is being thinned by etching. Then, wirings in the through holes and the second wiring are formed. The thinned glass substrate has a thickness of 50 μm or more and 300 μm or less. The through holes have the shape of a truncated cone.

    Abstract: A display is provided with a periodic structure that is dielectric and includes a support and a plurality of periodic elements. A plurality of periodic elements is arranged on a reference plane in a two-dimensional lattice form having a sub-wavelength period and are either convexities projected or concavities recessed in the reference plane. A metal layer is disposed on a surface of the periodic structure. The surface corresponds to a plane including a region of the reference plane surrounding the individual periodic elements and surfaces of the periodic elements. The metal layer's profile conforms to a surface profile of the periodic structure. The plurality of periodic elements have an interval therebetween in a first direction in which the plurality of periodic elements are arranged in a two-dimensional lattice form. The interval is different from an interval between the periodic elements in a second direction intersecting the first direction.

    Abstract: A loop antenna unit including two loop antennas having a same number of turns and different winding directions, the two loop antennas being positioned in line symmetry and not superposed on each other in a plan view. Each of the two loop antennas includes a loop conductive line wound continuously in one direction with n turns, where n is an integer of 3 or more, forming loops from a start point to an end point on the outermost loop or the innermost loop, the loop conductive line being bent in a transitional region in a direction from an outer loop toward an inner loop such that the loops have bent portions positioned side by side from an outermost first loop to an (n−1)th loop in the transitional region, and a jumper wire positioned on the insulating layer to cross the transitional region in a plan view.

    Abstract: A decorative sheet comprises a substrate layer; a pattern layer provided on the first front surface of the substrate layer; and a thermoplastic resin layer provided on the second front surface of the pattern layer. A test piece of 8 mm width from the decorative sheet is taken; the storage modulus is measured with an initial chuck distance of 10.77 mm, a start temperature of 30° C., an end temperature of 150° C., a temperature increase rate of 5° C./min, and a measurement frequency of 1.0 Hz. The ratio of the difference between the second storage modulus and a third storage modulus when the decorative sheet changes from the transition region to a rubbery flat region to the difference between a first storage modulus when the environmental temperature is 30° C. and a second storage modulus when the decorative sheet changes from a glassy region to a transition region is 3.5 or less.
