A method of producing a liquid crystal panel includes a grinding process and a sealing process. The grinding process includes grinding at least one common liquid crystal panel including a liquid crystal layer, a pair of boards that sandwich the liquid crystal layer, and a frame-shaped sealing member sandwiched between the boards along the non-rectangular outline to remove a section of the sealing member and to leave a rest of the sealing member. The grinding process further includes forming a sealing member removed processed edge section of the common liquid crystal panel. The sealing member removed processed edge section includes edges of the boards corresponding to the section of the sealing member removed from the common liquid crystal panel. The sealing process includes applying a sealing resin to the sealing member removed processed edge section to fill a space between the edges of the board.

Various embodiments provide a substrate processing apparatus for grinding a substrate, and a display device including a substrate in which a hole is formed in an edge of the substrate using the substrate processing apparatus. The substrate processing apparatus for processing a display substrate includes a body which, in operation, rotates, a cylindrical grinding part connected to the body, and a lateral groove formed in a surface of the cylindrical grinding part. The lateral groove is configured to accommodate the display substrate. Thus, it is possible to form a hole by grinding an edge of the display substrate so as to be matched with a designed value.

A vehicular interior rearview mirror assembly includes a mounting portion, a mirror casing and a mirror reflective element. The reflective element includes a glass substrate having a planar front surface, a planar rear surface and a circumferential perimeter edge around a periphery of the glass substrate that extends across a thickness dimension separating the planar front surface from the planar rear surface. A front perimeter edge portion of the circumferential perimeter edge includes a rounded glass surface circumferentially around the periphery of the glass substrate, with the rounded glass surface at least partially spanning the thickness dimension of the glass substrate. The rounded glass surface has a radius of curvature of at least 2.5 mm. The planar rear surface of the glass substrate is coated with a coating. No portion of the mirror casing overlaps onto the rounded glass surface of the glass substrate.

A method of making a mirror substrate for a vehicular rearview mirror assembly includes providing a glass substrate having a planar front surface, a planar rear surface and a circumferential perimeter edge. The glass substrate is positioned at a fixture and the front perimeter edge portion of the glass substrate is ground by moving a grinding wheel around the periphery of the glass substrate to establish a rounded surface about and around the periphery of the glass substrate and between the planar front surface and a rear portion of the perimeter edge of the glass substrate. The rounded surface has a radius of curvature of at least 2.5 mm. The rounded surface provides a curved transition between the planar front surface of the glass substrate and the rear portion of the perimeter edge of the glass substrate. The planar rear surface of the glass substrate is coated with a coating.

A vehicular interior rearview mirror assembly includes a mirror casing and an electro-optic mirror reflective element. The front glass substrate of the reflective element has a planar first surface, a planar second surface and a periphery surface extending therebetween. The mirror casing includes a central mounting element and two spaced apart attachment surfaces. The rear glass substrate of the reflective element is adhesively attached at the attachment surfaces. The central mounting element includes a pivot element that pivotally mounts at a mounting structure. A central cavity exists between the central mounting element and the rear glass substrate. The mirror assembly includes a curved outer surface that provides a rounded transition between the planar first surface of the front glass substrate and a less-curved outer surface of a side all of the mirror casing. No part of the mirror casing encroaches onto the planar first surface of the front glass substrate.
