1. A curved glass article, comprising:
a glass sheet comprising a first major surface and a second major surface opposite to the first major surface, the glass sheet being bent into a curved configuration defining a curved region disposed between a first flat section and a second flat section, the curved region comprising a radius of curvature of at least 250 mm;
a carrier adhered to the second major surface of the glass sheet and configured to maintain the glass sheet in the curved configuration, the carrier comprising a first longitudinal strip, a second longitudinal strip, a first lateral strip, and a second lateral strip, wherein the first longitudinal strip is spaced apart from the second longitudinal strip, wherein the first longitudinal strip and the second longitudinal strip define the radius of curvature of the curved region, wherein the first lateral strip is spaced apart from the second lateral strip, and wherein the first lateral strip and the second lateral strip extend between the first longitudinal strip to the second longitudinal strip, wherein the carrier is adhered to the second major surface by an adhesive that is bonded to the carrier and the glass sheet;
wherein the glass sheet deviates 0.3 mm or less from planar in the first flat section and in the second flat section;
wherein the first longitudinal strip and the second longitudinal strip each have a width Wlong of 2 mm or less;
wherein the first lateral strip and the second lateral strip each have a width Wlat of 20 mm or less, wherein at least a portion of the width Wlat of the first lateral strip is located in the curved region and in first flat section, and wherein at least a portion of the width Wlat of the second lateral strip is located in the curved region and in the second flat section, and
wherein no more than 10 mm of the width Wlat of the first lateral strip and of the second lateral strip is located in the first flat section or the second flat section, respectively.
