Abstract
A glass substrate includes at least one surface including an uneven surface having a difference of less than about 0.003 micrometers between a highest point and a lowest point in a section of the glass substrate, the section having a width of about 10 millimeters to about 30 millimeters, and the uneven surfaces being defined by continuously supplying molten glass onto molten metal and cooling the molten glass which floats on the molten metal.
Claims25
A glass substrate comprising:
- an uneven surface having a distance in a first direction of less than about 0.003 micrometers between a highest point and a lowest point in a section of the glass substrate, the section having a width in a second direction substantially perpendicular to the first direction of about 10 millimeters to about 30 millimeters,
- wherein the uneven surface of the glass substrate is defined by continuously supplying molten glass onto molten metal and cooling the molten glass which floats on the molten metal.
A display device comprising:
- an upper substrate;
- and
- a lower substrate which faces the upper substrate and comprises a thin-film transistor,
- wherein at least one of the upper substrate and the lower substrate comprises a glass substrate including at least one surface which is an uneven surface having a distance of less than about 0.003 micrometers between a highest point and a lowest point in a section of the respective substrate, the section having a width of about 10 millimeters to about 30 millimeters, and the uneven surface being defined by continuously supplying molten glass onto molten metal and cooling the molten glass which floats on the molten metal.
