Display device
To prevent a reduction in load resistance of a liquid crystal panel which is caused along with a reduction in thickness thereof, tempered glass is entirely bonded to both of front and back surfaces or one of the surfaces of the liquid crystal panel using an optical adhesive, and an amount of warp by which the liquid crystal panel alone is broken due to a pressure is set equal to or larger than that in a case of the tempered glass.
1. A display device, comprising:
a display panel including opposed transparent glass substrates each having a thickness of 0.1 mm;
a first transparent plate bonded to at least one of a front surface and a back surface of the display panel via an optical adhesive layer; and
a second transparent plate bonded to the first transparent plate via an optical adhesive layer,
wherein the first transparent plate comprises tempered glass having a thickness of 0.5 mm or larger, and
wherein an amount of warp by which the display panel alone is broken due to a pressure applied thereto is equal to or larger than an amount of warp by which the first transparent plate alone is broken due to a pressure applied thereto.
2. A display device, comprising:
a display panel including opposed transparent glass substrates each having a thickness of 0.1 mm;
a first transparent plate bonded to a front surface of the display panel via an optical adhesive layer; and
a second transparent plate bonded to a back surface of the display panel via an optical adhesive layer,
wherein the first and second transparent plates each comprises tempered glass having a thickness of 0.5 mm or larger,
wherein the optical adhesive layer for bonding the second transparent plate to the back surface of the display panel is larger in thickness than the optical adhesive layer for bonding the first transparent plate to the front surface of the display panel, and
wherein an amount of warp by which the display panel alone is broken due to a pressure applied thereto is equal to or larger than an amount of warp by which the first transparent plate alone is broken due to a pressure applied thereto.
3. A display device, comprising:
a display panel including opposed transparent glass substrates each having a thickness of 0.1 mm;
a first transparent plate bonded to a front surface of the display panel via an optical adhesive layer; and
a second transparent plate bonded to a back surface of the display panel via an optical adhesive layer,
wherein the first transparent plate has a thickness of 0.5 mm or larger and is comprised of tempered glass,
wherein the second transparent plate has a thickness of 0.5 mm or larger and is comprised of glass, acrylic (PMMA), polycarbonate, quartz or sapphire, and
wherein an amount of warp by which the display panel alone is broken due to a pressure applied thereto is equal to or larger than an amount of warp by which the first transparent plate alone is broken due to a pressure applied thereto.
4. A display device according to claim 3 , wherein:
the display panel comprises a non-self light emission type display panel; and
the second transparent plate which is bonded to the back surface of the display panel has diffusion characteristics.
5. A display device according to claim 4 , wherein the transparent substrates comprise two glass substrates each having a thickness of 0.1 mm.
6. A display device according to claim 5 , wherein each transparent plate comprises tempered glass having a thickness of 0.5 mm or larger.
7. A display device according to claim 3 ; wherein both the first and second transparent plates are comprised of tempered glass.
