A glass shaping method capable of grinding and/or polishing a fine brittle material more stably than conventional methods is provided. The glass shaping method of the present invention comprises: a mold forming step of shaping a surface of a base material having a higher melting temperature than a glass softening point to form a mold 10; a glass molding step of sealing softened glass into a groove 15 formed in a surface of the mold 10 by the forming step to mold a glass substrate 17; a glass processing step of cutting, grinding and/or polishing the glass substrate 17, with the mold 10 being fixed, to form a glass shaped article 1; and a step of eliminating only the base material 16 of the mold 10 after the glass processing step to remove the glass shaped article 1 from the mold.

Letting a particle diameter be Dx (m) when a cumulative particle volume cumulated from the small particle diameter side reaches x(%) of the total particle volume in a particle size distribution obtained regarding cerium oxide included in a polishing liquid using a laser diffraction/scattering method, D5 is 1 m or less, and a difference between D95 and D5 is 3 m or more.

A method for the zonal polishing of a workpiece includes using a polishing tool to guide a structured polishing pad over the surface of workpiece to remove material from the workpiece. A structured polishing pad includes a structuring adapted to the movement of a polishing tool.

The present disclosure provides a device for repairing appearance defects and repair method. The device comprises: a moving platform and at least one repair mechanism, each the repair mechanism comprises at least one sub-repair mechanism, each the sub-repair mechanism comprises a first moving portion, a second moving portion, and a repair portion; the moving platform is configured to support an apparatus to be repaired and move in a first direction to drive the apparatus to be repaired to move in the first direction; the first moving portion is configured to move in a second direction to drive the repair portion to move in the second direction, and the second direction intersects the first direction perpendicularly; the second moving portion is configured to move in a third direction to drive the repair portion to move in the third direction.

A display device includes first and second substrates each including a short side and a long side, ground parts located on at least one of the short and long sides of each of the first and second substrates and including at least one first ground surfaces, which are perpendicular to opposing surfaces of the first and second substrates, and at least one second ground surfaces, which are provided at at least one edge of the second substrate to define an obtuse angle with reference to the first ground surfaces, and unevenness disposed on the first ground surfaces along a first direction, where the unevenness defines an acute angle with reference to a normal line to the opposing surfaces.

In a method for manufacturing a glass plate that includes chamfering processing for chamfering an edge surface of a glass plate, the chamfering processing includes a step of forming a chamfered surface by irradiating the edge surface of the glass plate with a laser beam, and a step of heating the glass plate before the chamfered surface is formed. When a temperature of the glass blank at which the glass blank is heated is Tp [ C.], a glass transition point of the glass blank is Tg [ C.], and an average coefficient of linear thermal expansion of the glass blank is [1/ C.], (TgTp)5.6710.sup.7.Math.+840 is satisfied.

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.
