GLASS SUBSTRATE FOR DISPLAY FILTER

摘要

A light display front filter glass substrate having a predetermined strength without degradation in the display quality, and a display device using the display filter substrate. This display filter substrate is made of a glass substrate and has at least one of functions including an electromagnetic wave shielding function, a near infrared ray cutting function and a reflection preventing function, wherein the glass substrate has a thickness of 1.8 to 3.2 mm, an average value of the surface compressive stress of 20 to 70 MPa, and a warpage of 1.0 % or less. The surface compressive stress is given by a forced-air-cooled reinforcement or a chemical reinforcing treatment. This display filter substrate is arranged along the display face of the display device. ® KIPO & WIPO 2007
