Abstract

To improve the mechanical strength of a display panel configuring a display device, and provide a display device with an increased impact strength. A display device has a color filter or a thin film transistor formed on a glass substrate, and a polarizing plate attached to the glass substrate with an adhesive, wherein a resin film having no viscosity or adhesion is disposed on the polarizing plate side surface of the glass substrate.

Claims (26)

1 . A display device having a thin film transistor or a color filter formed on a glass substrate, and a polarizing plate attached to the glass substrate with an adhesive, wherein

a resin film having no viscosity or adhesion is disposed on the polarizing plate side surface of the glass substrate.

2 . The display device according to claim 1 , wherein

the polarizing plate is attached to the resin film with an adhesive.

3 . The display device according to claim 1 , wherein

a plastic substrate is attached to the resin film with an adhesive, and furthermore, the polarizing plate is attached to the plastic substrate with an adhesive.

4 . The display device according to claim 1 , comprising:

a display panel in which a thin film transistor is formed on the glass substrate, a color filter is formed on a plastic substrate, and the glass substrate and plastic substrate are disposed opposed to each other, wherein

another plastic substrate is attached to the resin film of the glass substrate with an adhesive, and furthermore, the polarizing plate is attached to the other plastic substrate with an adhesive.

5 . The display device according to claim 1 , wherein

the resin film is formed in only an area close to the perimeter of the glass substrate.

6 . The display device according to claim 1 , wherein

the resin film is such that an ultraviolet curable or heat curable resin is applied as a coating, and thereafter, cured.

7 . The display device according to claim 1 , wherein

the retardation of the resin film is 5 nm or less.

8 . The display device according to claim 1 , wherein

the thickness of the resin film is 100 μm or less.

9 . A display device having a thin film transistor layer, including a thin film transistor, provided on a glass substrate, the glass substrate being removed from the thin film transistor layer, and a polarizing plate being attached to the thin film transistor layer with an adhesive, wherein

a resin film having no viscosity or adhesion is disposed on the polarizing plate side surface of the thin film transistor layer,

a plastic substrate is attached to the resin film with an adhesive, and furthermore, the polarizing plate is attached to the plastic substrate with an adhesive.

10 . The display device according to claim 1 , wherein

the thickness of the glass substrate is 0.15 mm or less.

11 . The display device according to claim 1 , wherein

the thickness of the glass substrate is 0.05 mm or less.

12 . The display device according to claim 1 , being a liquid crystal display device.

13 . The display device according to claim 1 , being an organic EL display device.
