Abstract

The present invention provides a display device having no less flexibility even in the case where a plate, such as a polarizing plate, is provided to the display cell with the distortion of the image being controllable, and the display device has a display cell DC on which an image can be displayed and a plate (PP 1, 2 ) pasted to at least one side of the above described display cell, wherein the adhesiveness of the display cell to the plate in the direction perpendicular to the surface of the display cell that faces the plate is greater than the adhesiveness in the direction parallel to the facing surface.

Claims (24)

1 . A display device, comprising a display cell on which an image can be displayed and a plate pasted to at least one side of said display cell, characterized in that

an adhesiveness of the display cell to the plate in a direction perpendicular to a surface of the display cell that faces the plate is greater than an adhesiveness in a direction parallel to the surface.

2 . The display device according to claim 1 , characterized in that a liquid is intervened between the display cell and the plate.

3 . The display device according to claim 2 , characterized in that the liquid is a viscous fluid, has surface energy that is lower than the surface energy of the display cell and the surface energy of the plate, and has a boiling point of 200° C. or higher.

4 . The display device according to claim 2 , characterized in that the display cell has a substrate and the difference in the index of refraction between the liquid and the substrate is 0.2 or less.

5 . The display device according to claim 3 , characterized in that the display cell has a substrate and the difference in the index of refraction between the liquid and the substrate is 0.2 or less.

6 . The display device according to claim 2 , characterized in that a main component of the liquid is a phthalate-based material or benzyl benzoate.

7 . The display device according to claim 3 , characterized in that a main component of the liquid is a phthalate-based material or benzyl benzoate.

8 . The display device according to claim 1 , characterized in that the plate is a polarizing plate.

9 . The display device according to claim 2 , characterized in that the plate is a polarizing plate.

10 . The display device according to claim 1 , characterized in that the display cell has a substrate and the substrate is a plastic substrate.

11 . The display device according to claim 2 , characterized in that the display cell has a substrate and the substrate is a plastic substrate.

12 . The display device according to claim 1 , characterized in that the display cell has a substrate and the substrate is a glass substrate having a thickness of 100 μm or less.

13 . The display device according to claim 2 , characterized in that the display cell has a substrate and the substrate is a glass substrate having a thickness of 100 μm or less.

14 . The display device according to claim 13 , characterized in that the substrate has a thickness of 50 μm or less.

15 . The display device according to claim 1 , characterized by having a support member that makes contact with the plate through at least two points.

16 . The display device according to claim 2 , characterized by having a support member that makes contact with the plate through at least two points.

17 . The display device according to claim 16 , characterized in that the support member is a frame from which the center portion of the plate is exposed and which covers the peripheral portion of the plate and has two or more protrusions that make contact with the plate.

18 . The display device according to claim 3 , characterized in that

the plate is a polarizing plate,

the display device has a support member which makes contact with the polarizing plate through at least two points, and

the support member is a frame from which the center portion of the plate is exposed and which covers the peripheral portion of the plate and has two or more protrusions which make contact with the plate.

19 . The display device according to claim 18 , characterized in that the display cell has a substrate and the difference in the index of refraction between the liquid and the substrate is 0.2 or less.

20 . The display device according to claim 18 , characterized in that a main component of the liquid is a phthalate-based material or benzyl benzoate.
