Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.

A sheet-like spacer to be used when a laminate of a plurality of subs rates is formed for the purpose of processing end faces of the substrates is provided between the adjacent substrates in the laminate to keep the adjacent substrates apart from each other. An area of the spacer is smaller than that of the substrates. A contact angle of a surface of the spacer with respect to pure water is 50° or less.

A method for processing into an aspheric lens, includes: a preprocessing step of performing preprocessing on a glass substrate; and an etching step of performing wet etching on the glass substrate subjected to the preprocessing. The preprocessing step includes a step of irradiating a certain position of the glass substrate with a pulsed laser beam such that a partial region inside the glass substrate is modified, thereby generating a density distribution in a thickness direction at the position irradiated with the pulsed laser beam, or a step of forming a predetermined wedge-shaped concave portion in a surface of the glass substrate by use of a chemical or physical processing method.
