1. A display device comprising:
a display panel; and
a front stacked structure on a front surface of the display panel;
wherein the front stacked structure includes a cover window and a bonding member,
the bonding member includes a window bonding member attached to the cover window,
the cover window includes ultra-thin glass having a thickness in a range of about 10 μm to about 300 μm,
the ultra-thin glass includes a first compressive region extending from a first surface thereof to a first compression depth, a second compressive region extending from a second surface thereof to a second compression depth, and a tensile region disposed between the first compression region and the second compression region,
a total compressive stress in the ultra-thin glass is the same as a total tensile stress in the ultra-thin glass,
the window bonding member is attached to the ultra-thin glass,
the window bonding member attached to the ultra-thin glass includes a silane compound containing an epoxy series reactive functional group, and
wherein the silane compound includes any one of 3-glycidoxypropyltriethoxysilane, 3-glycidoxypropylmethyldiethoxysilane, and 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane,
wherein the front stacked structure further includes a polarization member disposed between the display panel and the cover window and a polarization member bonding member which attaches the polarization member to the front surface of the display panel,
a peeling force of the window bonding member is greater than a peeling force of the polarization member bonding member,
the front stacked structure further includes an impact absorbing layer disposed between the polarization member and the cover window and an impact absorbing layer bonding member which attaches the impact absorbing layer to the polarization member, and
a peeling force of the window bonding member is greater than a peeling force of the impact absorbing layer bonding member.
